Ethylene Diamine (Product Code: SCL-839/163) is a colourless, strongly basic liquid amine used as a bidentate ligand to prepare coordination complexes in college and university chemistry laboratories. Also written ethylenediamine and abbreviated “en”, it is offered as a 500ml analytical reagent with an MSDS for inorganic practicals that demonstrate ligand exchange and the chelate effect. It is supplied by Jain Scientific Equipments Pvt Ltd (ScienceLab), Ambala, India, a lab consumables supplier in India for colleges, universities and research groups.

Specifications

What Is Ethylene Diamine Used For?

Adding ethylenediamine drop by drop to a pale green nickel(II) solution changes the colour through blue to violet as the two-nitrogen ligand displaces water molecules around the metal ion, giving students a vivid picture of ligand substitution. Similar colour shifts can be seen with copper(II), and cobalt salts are used in preparative practicals where the solid complex is crystallised, filtered and characterised. Comparing these complexes with the ammonia versions is a neat way to introduce the chelate effect in lab equipment for college inorganic courses.

The liquid is corrosive to skin and eyes, has a strong ammonia-like smell and can irritate the airways, so measure it in a fume cupboard wearing gloves and goggles. It also absorbs moisture and carbon dioxide from air, so keep the cap tight, pour only what is needed into a clean measuring cylinder, and never return unused liquid to the stock bottle.

Supplier

Ethylene Diamine is supplied by Jain Scientific Equipments Private Limited, which trades as ScienceLab from Ambala, Haryana. The company sources ligands, metal salts and other reagents for teaching and research laboratories in India and international markets, and quotes them together with the glassware a coordination chemistry practical needs.

Fehling A Solution (Product Code: SCL-841/164) is the copper-containing half of Fehling’s reagent, used after mixing with Fehling B to detect reducing sugars and aliphatic aldehydes in school and college laboratories. Biology, organic chemistry and food-testing practicals rely on this 500 ml analytical reagent, supplied with an MSDS, for the familiar brick-red precipitate test. It is supplied by Jain Scientific Equipments Pvt Ltd (ScienceLab), Ambala, India, a laboratory chemicals supplier in India.

Specifications

What Is Fehling A Solution Used For?

Equal volumes of Fehling A and Fehling B are poured into a test tube to give a deep blue mixture, the sample is added, and the tube is warmed in a water bath or over a gentle flame. Glucose, fructose, maltose and simple aliphatic aldehydes such as formaldehyde reduce the copper(II) ions, and a red to orange precipitate of copper(I) oxide settles out. Sucrose, most ketones and aromatic aldehydes such as benzaldehyde do not give this result, which lets students separate these groups in functional-group analysis. Stocking both halves as a Fehling solution kit keeps these tests ready for every batch.

The two solutions are stored apart because the mixed reagent does not keep; combine only the amount required for the day’s tests. Copper sulphate solution is harmful if swallowed and irritating to the eyes, so pupils should use test-tube holders when heating and wash hands after the practical.

Supplier

ScienceLab is the trading name of Jain Scientific Equipments Private Limited in Ambala, Haryana, which supplies Fehling A Solution among its prepared reagents. The company sources reagents and chemicals for schools, colleges and food-testing laboratories in India and international markets, so both halves of Fehling’s reagent can be quoted in one enquiry. See the company profile for background.

Frequently Asked Questions

Is Fehling B included with Fehling A Solution?
No. This listing is for Fehling A Solution only, in a 500 ml pack. Fehling B Solution is a separate product, and both halves are needed to carry out the test, so order them together in matching quantities.

In what ratio are Fehling A Solution and Fehling B mixed?
Fehling A Solution and Fehling B are normally mixed in equal volumes immediately before use to give a deep blue reagent. Mix only the amount required for the day’s tests, because the combined reagent does not keep.

Why is Fehling A Solution not supplied ready-mixed with Fehling B?
Fehling A Solution is kept separate because, once combined with Fehling B, the copper-tartrate complex slowly decomposes. Storing the two halves apart preserves the reagent until the moment it is needed for a reducing-sugar or aldehyde test.

What is the shelf life of Fehling A Solution?
The shelf life of Fehling A Solution depends on the chemical, its grade and storage conditions, so no fixed period is stated here. Ask us for the expiry date of the batch you are quoted, and store the bottle capped and away from direct sunlight.

Can Benedict’s reagent be used instead of Fehling A Solution?
Benedict’s reagent detects the same reducing sugars in a single, milder solution and can replace Fehling A Solution with Fehling B for many sugar tests. Many syllabi still specify Fehling’s test for aldehydes, so check your practical manual first.

Who supplies Fehling A Solution (SCL-841/164)?
Fehling A Solution (SCL-841/164) is supplied by Jain Scientific Equipments Pvt Ltd (ScienceLab) of Ambala, Haryana, India. The company provides prepared reagents, including both Fehling solutions, to schools, colleges and food-testing laboratories in India and international markets.

What should a school include in a Fehling A Solution order enquiry?

Fehling B Solution (Product Code: SCL-843/165) is the colourless, alkaline tartrate half of Fehling’s reagent, used with Fehling A to test for reducing sugars and aliphatic aldehydes in school, college and food-testing laboratories. It provides the alkaline conditions and the tartrate that keeps copper in solution, and is packed as a 500 ml analytical reagent with an MSDS. It is supplied by Jain Scientific Equipments Pvt Ltd (ScienceLab), Ambala, India, a lab consumables supplier in India.

Specifications

What Is Fehling B Solution Used For?

Without the tartrate in solution B, copper(II) ions would simply precipitate as copper hydroxide in alkali; instead they form a soluble deep blue complex that is ready to be reduced. When a sugar solution such as fructose or glucose is heated with the mixed reagent, a red precipitate forms, while sucrose stays blue unless it has first been hydrolysed with acid. Food and nutrition laboratories also use the paired Fehling solutions in the Lane-Eynon titration to estimate reducing sugars, a method that often appears in a food-science volumetric analysis kit.

Being strongly alkaline, solution B can burn skin and damage eyes, so wear gloves and goggles while dispensing. Alkaline solutions tend to seize ground-glass stoppers, so a bottle with a plastic or rubber closure is more practical for bench use, and the cap should be kept tight so the solution does not absorb carbon dioxide from the air.

Supplier

Fehling B Solution is supplied by Jain Scientific Equipments Private Limited, which trades as ScienceLab from Ambala, Haryana. The company sources prepared reagents for educational and testing laboratories in India and international markets. For institutional and tender buyers who need vendor registration details, the supplying company’s GSTIN is 06AAECJ8618A1ZT and its LEI is 3358004HRD1JIVXKYX49.

Frequently Asked Questions

Does the Fehling B Solution pack contain both Fehling solutions?
No. The Fehling B Solution pack contains 500 ml of solution B only. Fehling A Solution, the copper half, is listed separately, and both are needed for the reducing-sugar and aldehyde tests, so order the two together.

What is the role of Fehling B Solution in the test?
Fehling B Solution provides the alkaline medium and the tartrate that holds copper(II) ions in solution. Without it, copper would precipitate as hydroxide; with it, a reducing sample can convert the copper to red copper(I) oxide.

Is Fehling B Solution dangerous to handle?
Fehling B Solution is corrosive because it is strongly alkaline, so it can burn skin and damage eyes. Wear gloves and eye protection when dispensing it, and follow the MSDS supplied with the pack for first aid and spill clean-up.

What is the shelf life of Fehling B Solution?
The shelf life of Fehling B Solution depends on the chemical, its grade and storage conditions, so we do not quote a fixed period. Ask us for the expiry date of the batch you are quoted, and keep the container closed to limit carbon dioxide uptake.

Who supplies Fehling B Solution (SCL-843/165)?
Fehling B Solution (SCL-843/165) is supplied by Jain Scientific Equipments Pvt Ltd, trading as ScienceLab, Ambala, Haryana, India. The company provides prepared reagents and laboratory consumables to schools, colleges and food-testing laboratories in India and international markets.

Ferric Chloride Anhydrous (Product Code: SCL-845/166) is the water-free form of iron(III) chloride, used to prepare the neutral ferric chloride reagent that identifies phenols, enols and acetate ions in chemistry laboratories. Teaching and industrial laboratories buy it as 500 gm of analytical reagent, packed with an MSDS, and college courses also use it as a Lewis acid catalyst in synthesis. It is supplied by Jain Scientific Equipments Pvt Ltd (ScienceLab), Ambala, India, a chemistry consumables supplier in India.

Specifications

What Is Ferric Chloride Anhydrous Used For?

For the phenol test, a dilute ferric chloride solution is neutralised with a few drops of dilute alkali until a faint permanent turbidity appears, then filtered. A drop added to phenol gives a violet colour, and salicylic acid and other enolic compounds give related violet to red shades. In anion analysis, the same neutral reagent turns a solution of an acetate deep red, and boiling throws down a brown precipitate, so it belongs in any school salt analysis kit. Iron(III) ions are also confirmed with potassium ferrocyanide (Prussian blue) and thiocyanate (blood-red).

The anhydrous solid is strongly hygroscopic and fumes in moist air, releasing hydrogen chloride, and it dissolves in water with noticeable heat. Open the pack only briefly, weigh quickly in a dry beaker, add the solid slowly to water rather than the reverse, and store the tightly sealed container in a dry cabinet away from metals it can corrode.

Supplier

Under the ScienceLab name, Jain Scientific Equipments Private Limited of Ambala, Haryana, supplies Ferric Chloride Anhydrous to schools, colleges and industry laboratories. The company sources identification-test reagents such as this one for customers in India and international markets, alongside the reagent bottles and glassware used to store and handle them. Details are on the ScienceLab company profile.

Frequently Asked Questions

What is the difference between Ferric Chloride Anhydrous and hydrated ferric chloride?
Ferric Chloride Anhydrous contains no water of crystallisation, so it carries more iron per gram than the hydrated salt. It absorbs moisture rapidly and fumes in damp air, which makes quick weighing and airtight storage essential.

How much Ferric Chloride Anhydrous is supplied per pack?
Each pack of Ferric Chloride Anhydrous (SCL-845/166) contains 500 gm of analytical reagent grade solid, supplied with an MSDS. Transfer a small working stock into a well-sealed reagent bottle so the main pack is opened as rarely as possible.

How is neutral ferric chloride made from Ferric Chloride Anhydrous?
To make neutral ferric chloride, dissolve a little Ferric Chloride Anhydrous in water, add dilute alkali drop by drop until a slight precipitate persists, then filter. Prepare the reagent fresh for each practical session for reliable phenol and acetate tests.

What safety precautions does Ferric Chloride Anhydrous need?
Ferric Chloride Anhydrous is corrosive and releases acid fumes when it meets moisture. Wear gloves and goggles, add the solid slowly to water rather than the reverse, and read the MSDS that comes with the product before use.

What is the shelf life of Ferric Chloride Anhydrous?
The shelf life of Ferric Chloride Anhydrous depends on the chemical, its grade and storage conditions, so no fixed period is given here. Ask us for the expiry date of the batch you are quoted through the contact page; once opened, keeping out humid air matters most.

Who supplies Ferric Chloride Anhydrous (SCL-845/166)?
Ferric Chloride Anhydrous (SCL-845/166) is supplied by Jain Scientific Equipments Pvt Ltd (ScienceLab), Ambala, Haryana, India. The company provides analysis reagents and laboratory glassware to schools, colleges and industrial laboratories in India and international markets.

Ferrous Ammonium sulphate (Product Code: SCL-847/167), widely known as Mohr’s salt, is a pale green iron(II) double salt used to prepare standard solutions for permanganate and dichromate titrations in chemistry laboratories. It resists air oxidation better than plain ferrous sulphate, which is why senior secondary schools and colleges weigh it out directly; each pack holds 500 gm of analytical reagent with an MSDS. It is supplied by Jain Scientific Equipments Pvt Ltd (ScienceLab), Ambala, India, a laboratory chemicals supplier in India.

Specifications

What Is Ferrous Ammonium Sulphate (Mohr’s Salt) Used For?

The best-known practical is the determination of the strength of a potassium permanganate solution. Students weigh Mohr’s salt accurately on a chemical balance, dissolve it in water containing some dilute sulphuric acid, make it up to the mark in a volumetric flask, and titrate portions against permanganate from a burette. No separate indicator is needed: the first lasting pale pink colour marks the end point. This experiment, together with its oxalic acid counterpart, forms the core of the redox section of a typical titration kit for schools.

Dilute sulphuric acid is added when dissolving the salt to stop hydrolysis and slow oxidation of iron(II) by air, so make the solution on the day of use. The salt also features in crystallisation practicals, where students prepare Mohr’s salt from ferrous sulphate and ammonium sulphate. Keep the stock container closed and dry; crystals that have turned yellowish-brown on the surface have partly oxidised and are no longer suitable as a standard.

Supplier

Jain Scientific Equipments Private Limited, which presents itself to customers as ScienceLab, supplies Ferrous Ammonium sulphate from Ambala, Haryana. The company sources titration reagents such as Mohr’s salt and quotes them with burettes, flasks and other glassware for institutions in India and international markets. See the company profile.

Frequently Asked Questions

Is Ferrous Ammonium sulphate the same as Mohr’s salt?
Yes. Ferrous Ammonium sulphate is the chemical name of Mohr’s salt, the pale green iron(II) ammonium double sulphate. Syllabi and practical manuals use both names for the same compound, so either name can be used in an enquiry.

Why is Ferrous Ammonium sulphate preferred over ferrous sulphate for standard solutions?
Ferrous Ammonium sulphate is more stable in air than ferrous sulphate, so its iron(II) content stays reliable enough to weigh out directly as a standard. Ferrous sulphate oxidises more readily, which makes its solutions less dependable for accurate titration work.

How much Ferrous Ammonium sulphate is in a pack, and what grade is it?
Each pack of Ferrous Ammonium sulphate (SCL-847/167) contains 500 gm of analytical reagent grade material, supplied with an MSDS. The pack serves the permanganate and dichromate titrations that make up the redox section of a practical course.

What is the shelf life of Ferrous Ammonium sulphate?
The shelf life of Ferrous Ammonium sulphate depends on the chemical, its grade and storage conditions, so no fixed expiry period is quoted. Ask us for the expiry date of the batch you are quoted, and store the crystals sealed and dry to limit surface oxidation.

Can I request a batch assay report for Ferrous Ammonium sulphate?
Ferrous Ammonium sulphate is listed as analytical reagent grade and supplied with an MSDS. If your laboratory needs a batch assay report or other documents, please contact us before ordering so we can confirm what is available.

Who supplies Ferrous Ammonium sulphate (SCL-847/167)?
Ferrous Ammonium sulphate (SCL-847/167) is supplied by Jain Scientific Equipments Pvt Ltd, trading as ScienceLab, Ambala, Haryana, India. The company provides titration reagents and glassware to senior secondary schools and colleges in India and international markets.

What should an institutional order request for Ferrous Ammonium sulphate include?

Ferrous Sulphate (Product Code: SCL-849/168) is an iron(II) salt, traditionally called green vitriol, used for the brown ring test for nitrates and for thermal decomposition activities in school and college chemistry laboratories. Teachers also use it as the starting material when students prepare Mohr’s salt, and it is packed as 500 gm of analytical reagent with an MSDS. It is supplied by Jain Scientific Equipments Pvt Ltd (ScienceLab), Ambala, India, a lab consumables supplier in India for schools, colleges and training institutes.

Specifications

What Is Ferrous Sulphate Used For?

In the brown ring test, a freshly made ferrous sulphate solution is mixed with the suspected nitrate solution, and concentrated sulphuric acid is poured carefully down the side of the tilted tube so that it forms a lower layer. A brown ring at the boundary confirms nitrate. Heating a few crystals in a dry test tube is another favourite: the green crystals lose water, then decompose with the sharp smell of sulphur oxides, leaving a reddish-brown residue, a clear example of a decomposition reaction. Both activities make ferrous sulphate a routine purchase alongside school chemistry lab equipment in India.

Iron(II) ions can be confirmed with potassium ferricyanide, which gives a deep blue precipitate. Because ferrous sulphate slowly oxidises in air, its solution must be prepared just before the test, ideally with a few drops of dilute sulphuric acid; crystals that have turned yellowish-brown on the surface have partly oxidised. Keep the container tightly closed in a cool, dry place and carry out the heating activity in a ventilated room.

Supplier

Jain Scientific Equipments Private Limited operates under the ScienceLab brand in Ambala, Haryana, and supplies Ferrous Sulphate as part of its practical-class reagent range. It sources chemicals for schools, colleges and training institutes in India and international markets, so a department can order reagents and glassware together. More is available on the company profile page.

Frequently Asked Questions

What quantity and grade of Ferrous Sulphate are supplied?
Ferrous Sulphate (SCL-849/168) is supplied as 500 gm of analytical reagent grade iron(II) sulphate per pack, with an MSDS. Only a few crystals are needed for each brown ring test or decomposition activity, so weigh out small portions as required.

Why must Ferrous Sulphate solution be freshly prepared for the brown ring test?
Ferrous Sulphate solution must be fresh because iron(II) oxidises to iron(III) on standing, and an oxidised solution gives a weak or missing brown ring. Dissolve a small amount just before the test, ideally with a few drops of dilute sulphuric acid.

Is Ferrous Sulphate hazardous?
Ferrous Sulphate is harmful if swallowed and can irritate eyes and skin, while the concentrated sulphuric acid used in the brown ring test is the bigger hazard. Follow the MSDS supplied with the pack and supervise students closely during acid layering.

What is the shelf life of Ferrous Sulphate?
The shelf life of Ferrous Sulphate depends on the chemical, its grade and storage conditions, so this page gives no fixed period. Ask us for the expiry date of the batch you are quoted; airtight, dry storage keeps the crystals green and usable.

Ferrous Sulphide sticks (Product Code: SCL-851/169) are sticks of iron(II) sulphide used with dilute acid to generate hydrogen sulphide gas for qualitative inorganic analysis in school and college chemistry laboratories. The stick form suits the middle bulb of a Kipp-type generator, and each container holds 500 gm of analytical reagent sent with its MSDS. They are supplied by Jain Scientific Equipments Pvt Ltd (ScienceLab), Ambala, India, a laboratory chemicals supplier in India for practical rooms.

Specifications

What Are Ferrous Sulphide Sticks Used For?

In the salt analysis practical of senior secondary and college courses, hydrogen sulphide is the group reagent that precipitates Group II cations as sulphides from acidified solution and Group IV cations from ammoniacal solution. Staff charge a Kipp generator with the sticks and fill the reservoir with dilute hydrochloric or dilute sulphuric acid. Opening the tap sends a steady stream of gas through the test solution; closing it pushes the acid away from the sticks and stops the reaction without dismantling anything. For occasional use, a Woulf bottle or a boiling tube fitted with a thistle funnel and delivery tube does the same job on a smaller scale.

Hydrogen sulphide is toxic, and its rotten-egg smell fades quickly because the nose tires of it, so the generator should run only inside a fume cupboard and be drained of acid at the end of the session. Keep the sticks in a closed container in a dry place, well away from acids: moist air slowly weathers the surface, and any contact with acid releases gas at once.

Supplier

Ferrous Sulphide sticks are supplied by Jain Scientific Equipments Private Limited, which trades as ScienceLab from Ambala, Haryana. The company sources practical reagents alongside the laboratory apparatus it offers, so schools and colleges can order glassware and chemicals from one source. For vendor registration, the supplying company is Jain Scientific Equipments Private Limited (CIN U29309HR2020PTC087597, GSTIN 06AAECJ8618A1ZT). Read more on our company profile.

Related Chemistry Lab Products

Generating hydrogen sulphide needs an acid, a vessel to react it in, a way to confirm the gas and somewhere safe to work. These items complete the set-up:

• Hydrochloric Acid Dilute — the acid most often charged into the generator to react with the sticks.
• Sulphuric Acid Dilute — an alternative acid for producing the gas.
• Woulf Bottle — a multi-neck bottle that can serve as a small generator or as a wash bottle for the gas.
• Lead Acetate — for lead acetate paper, which turns black in hydrogen sulphide and confirms the gas is flowing.
• Polypropylene Ducted Fume Cupboard — extracts the toxic gas while the generator is running.

Browse the Chemistry Lab category for other salt analysis reagents, glassware and charts.

Frequently Asked Questions

Why are Ferrous Sulphide sticks sold as sticks rather than powder?
Ferrous Sulphide sticks load cleanly into a Kipp-type generator and rest on the constriction instead of falling into the acid below, so the gas flow stays controllable. A fine powder would react too fast and could block the apparatus.

Which acid should be used with Ferrous Sulphide sticks?
Dilute hydrochloric acid is the usual choice with Ferrous Sulphide sticks, and dilute sulphuric acid also works. Concentrated acids are avoided because they contaminate the hydrogen sulphide with acid fumes or oxidise it before it reaches the test solution.

What is included in a pack of Ferrous Sulphide sticks?
A pack of Ferrous Sulphide sticks (SCL-851/169) contains 500 gm of analytical reagent grade sticks together with the MSDS. The gas generator, acid and connecting tubing are separate items, which can be added to the same enquiry.

What is the shelf life of Ferrous Sulphide sticks?
The shelf life of Ferrous Sulphide sticks depends on the chemical, its grade and storage conditions, so no fixed period is stated. Ask us for the expiry date of the batch you are quoted, and keep the lid tight, because weathered sticks give a weaker gas stream.

Can a certificate of analysis be provided for Ferrous Sulphide sticks?
Ferrous Sulphide sticks are supplied with an MSDS. If your purchase procedure needs batch analysis documents, mention it through our contact page before ordering and we will tell you what can be provided for the batch being quoted.

Formaldehyde (Product Code: SCL-853/170) is the simplest aldehyde, a liquid reagent used for aldehyde identification tests, resin-making demonstrations and the preservation of biological specimens in school and college laboratories. Chemistry teachers use it as the reference compound when students learn to tell aldehydes from ketones, and it comes in a 500 ml analytical reagent bottle with an MSDS. It is supplied by Jain Scientific Equipments Pvt Ltd (ScienceLab), Ambala, India, a chemistry consumables supplier in India.

Specifications

What Is Formaldehyde Used For?

In the organic chemistry practical, a few drops of formaldehyde warmed with Tollens' reagent deposit a silver mirror inside a clean test tube, and with Fehling's solution it throws down a red precipitate of copper(I) oxide – the two classic results that separate aldehydes from ketones. Teachers also use it to make a phenol-formaldehyde or urea-formaldehyde resin in a boiling tube, a quick and memorable way to show condensation polymerisation when the polymers chapter comes up.

In biology, formaldehyde diluted with water (formalin) keeps specimens firm in sealed jars for museum and dissection work. The vapour irritates eyes and airways and formaldehyde is a recognised health hazard, so pour and dilute it inside a school fume cupboard while wearing goggles and gloves, keep specimen jars closed, and follow the MSDS for spills. If the bottle is kept somewhere very cold, the liquid can turn cloudy as a white solid (paraformaldehyde) separates; storing it at ordinary room temperature, away from light and oxidising agents, avoids this.

Supplier

Formaldehyde is supplied by Jain Scientific Equipments Private Limited, a private limited company that does business as ScienceLab in Ambala, Haryana. The company sources reagents such as this one for teaching institutions and distributors, so chemistry and biology departments can complete their practical lists in a single order. Background on the company is on the company profile page.

Formalin is the everyday name for formaldehyde dissolved in water. This Formaldehyde is supplied as a liquid in a 500 ml bottle; confirm its strength with us before ordering if you need to match a specific formalin specification for specimen work.

Why has the Formaldehyde become cloudy?
Formaldehyde can turn cloudy when stored somewhere very cold, because white paraformaldehyde separates out. Bringing the bottle back to room temperature may clear it; if it stays cloudy, contact us before using it for quantitative work.

Can students handle Formaldehyde directly?
Students can carry out Tollens' and Fehling's tests with a few drops of Formaldehyde under supervision. Decanting from the 500 ml bottle and diluting it for specimen jars should be left to staff working in a fume cupboard with goggles and gloves.

What is the shelf life of Formaldehyde?
The shelf life of Formaldehyde depends on the chemical, its grade and storage conditions, so we do not state a fixed period. Ask us for the expiry date of the batch you are quoted, keep the cap tight and store the bottle upright at room temperature.
