What Is Sodium Thiocyanate Used For?
For cation identification, a few drops of thiocyanate solution are added to the acidified test solution: an immediate blood-red colour from the iron-thiocyanate complex confirms iron(III). Iron(II) gives little colour until it is oxidised, so the test also helps students tell the two oxidation states apart. With cobalt(II), a concentrated thiocyanate solution and a little acetone develop a blue complex, a further confirmatory test used in college analysis.
The same reaction drives a much-used Le Chatelier's principle practical and features in many a chemistry teaching kit in India. A pale red mixture of dilute ferric chloride and thiocyanate is shared among several tubes; adding more iron(III) or more thiocyanate deepens the colour, while removing iron(III) or changing temperature shifts it the other way. Sodium thiocyanate is harmful if swallowed or absorbed, and contact with acids can release a very toxic gas, so keep it apart from acids and wash hands after use. The solid absorbs moisture from air, so close the container promptly.

Useful companions for iron(III) tests and the equilibrium practical:
- Ferric Chloride Anhydrous — the iron(III) source that forms the red complex
- Volumetric Flask — for making up the dilute stock solutions accurately
- Test Tube Racks — holds the comparison tubes side by side
- Dropper Bottle, 10 ml — small bottles for student reagent sets
- Acetone — intensifies the blue cobalt thiocyanate colour
More reagents for inorganic practicals are listed under Chemistry Lab.
Frequently Asked Questions
Will Sodium Thiocyanate detect iron(II)?
Not directly. Sodium thiocyanate gives only a faint colour with iron(II), so oxidise the sample first, for example with a drop of hydrogen peroxide, and then add the thiocyanate solution to see the blood-red iron(III) complex that confirms iron.
How is Sodium Thiocyanate used to teach chemical equilibrium?
Sodium thiocyanate is mixed with dilute iron(III) solution to give a pale red complex; students then add extra reactant, remove iron(III) or warm the tubes, and relate each colour change to the shift in equilibrium predicted by Le Chatelier's principle.
Why has the Sodium Thiocyanate become damp or caked?
Because sodium thiocyanate is strongly hygroscopic and pulls moisture from room air whenever the lid is open. Caking does not stop it working in qualitative tests, but storing the pack tightly closed in a dry cupboard prevents it.
What precautions does Sodium Thiocyanate need?
Sodium thiocyanate should not be swallowed, spilled on skin or inhaled as dust, and it must never be stored with or mixed into acids, which can release a very toxic gas. The MSDS supplied with the pack covers protective equipment, first aid and disposal.
What is the shelf life of Sodium Thiocyanate?
Shelf life depends on the chemical, its grade and storage conditions, so no fixed period is stated for this sodium thiocyanate. Ask us for the expiry date of the batch you are quoted, and keep the opened pack sealed and dry.
Who supplies Sodium Thiocyanate?
Sodium Thiocyanate is supplied by Jain Scientific Equipments Pvt Ltd, trading as ScienceLab, from Ambala, Haryana, India. The company sources this analytical reagent for schools, colleges, universities and dealers in India and international markets, and quotes it alongside other chemistry reagents.

Sodium Thiosulphate (Thio)
Sodium Thiosulphate (Thio) (Product Code: SCL-973/229) is an analytical reagent grade salt used as the reducing titrant in iodometric titrations and in rate-of-reaction experiments in school and college chemistry laboratories. Known on the bench simply as "thio" or "hypo", it comes as a 500 gm pack with its MSDS and is a staple of any volumetric analysis kit in India. It is supplied by Jain Scientific Equipments Pvt Ltd (ScienceLab), Ambala, India.

What Is Sodium Thiosulphate Used For?
In iodometric titrations, an oxidising sample such as a copper(II) salt or potassium dichromate is treated with excess potassium iodide, and the iodine set free is titrated with thiosulphate from a burette. Starch is added only when the colour has faded to pale straw, and the end point is the sharp change from blue-black to colourless. Where a standard iodine solution is kept in the lab, thiosulphate is its natural partner for cross-checking strength, which is why it belongs in every titration kit for schools in India.
For reaction kinetics, students mix thiosulphate solution with dilute hydrochloric acid in a flask standing on a paper marked with a cross and time how long the precipitating sulphur takes to hide the mark; repeating the run at different concentrations or temperatures gives clear, plottable results. Thiosulphate itself is of low hazard, but acidified mixtures give off sulphur dioxide, so run the kinetics experiment in a well-ventilated room and rinse flasks promptly to remove the sulphur deposit.

Frequently Asked Questions
What does "Thio" mean in Sodium Thiosulphate (Thio)?
"Thio" is the usual laboratory shorthand for sodium thiosulphate. Older textbooks and photographers call the same salt hypo, so all three names on a requisition list refer to this one analytical reagent, listed here as Sodium Thiosulphate (Thio).
How long do Sodium Thiosulphate solutions stay reliable?
Prepared sodium thiosulphate solutions slowly decompose, partly through bacterial action, so make them with freshly boiled and cooled distilled water, keep them stoppered away from light and re-standardise them before any quantitative work.
When should starch indicator be added in a Sodium Thiosulphate titration?
Add starch near the end point, once the iodine colour has faded to pale straw yellow. Adding it too early in a sodium thiosulphate titration binds iodine tightly into the blue complex, which makes the end point drag.
Is Sodium Thiosulphate hazardous?
Sodium thiosulphate is of low toxicity, but it reacts with acids to form sulphur dioxide and a sulphur precipitate, so the kinetics experiment should run in a ventilated room. Follow the MSDS supplied with each pack for storage, first aid and disposal.
What is the shelf life of Sodium Thiosulphate (Thio)?
No fixed shelf life is stated, because shelf life depends on the chemical, its grade and storage conditions. For Sodium Thiosulphate (Thio), ask us for the expiry date of the batch you are quoted, and keep the solid in a closed container in a cool, dry place.

Starch Powder
Starch Powder (Product Code: SCL-975/230) is an analytical reagent grade carbohydrate powder used to prepare starch indicator for iodine titrations and to run food tests in school and college laboratories. Even a trace of iodine turns it an intense blue-black, so chemistry departments use it at titration end points and biology teachers build it into the enzyme experiment kit for school practicals; it comes as a 500 gm pack with its MSDS. It is supplied by Jain Scientific Equipments Pvt Ltd (ScienceLab), Ambala, India.

| Product code | SCL-975/230 |
| Supplied by | Jain Scientific Equipments Pvt Ltd (ScienceLab), Ambala, India |
What Is Starch Powder Used For?
To make the indicator, a small amount of starch is stirred into a smooth paste with cold water and poured into boiling water, then heated briefly until the liquid turns translucent and allowed to cool. A few drops in an iodometric or iodimetric titration give a sharp change between blue-black and colourless at the end point, far easier to judge than the fading yellow of iodine alone. The prepared solution supports mould growth, so most laboratories make a fresh batch for each practical session.
In biology and home-science practicals, starch is the reference substance for the iodine food test and the starting material for digestion experiments. Students mix a starch suspension with saliva or diastase, remove drops at timed intervals onto a white tile with iodine until the blue colour no longer appears, and then confirm the sugar formed using Benedict solution, a combination that school laboratories in India repeat every year. Starch is of low hazard, but avoid raising dust clouds when weighing and keep the container sealed against damp.

Frequently Asked Questions
How long does indicator made from Starch Powder last?
Prepared starch indicator lasts only a short time, because the solution supports mould growth and loses sensitivity. Make a small fresh quantity from Starch Powder for each practical session rather than storing a large bottle of made-up indicator.
Why does the blue colour fade when Starch Powder indicator is warm?
Because the starch-iodine complex breaks apart on heating and re-forms on cooling. Titrations that use indicator made from Starch Powder should therefore be carried out at room temperature to keep the end point sharp and reliable.
Is Starch Powder the same as soluble starch?
This product is listed as Starch Powder, and the listing does not describe it as soluble starch. If your method specifically calls for soluble starch, contact us before ordering so we can confirm which listing suits your procedure.
Can biology departments use Starch Powder for food tests?
Yes. Starch Powder works as the positive control in the iodine food test and as the substrate in amylase digestion practicals, so one pack can serve both the chemistry and biology rooms of a school or college.
What is the shelf life of Starch Powder?
Shelf life depends on the chemical, its grade and storage conditions, so no blanket period is given for this Starch Powder. Ask us for the expiry date of the batch you are quoted, and keep the pack closed in a cool, dry place away from damp.

Strontium Bromide
Strontium Bromide (Product Code: SCL-977/231) is an analytical reagent grade strontium salt used to demonstrate the crimson strontium flame test and to identify the bromide ion in school and college salt analysis. One compound covers two tests, which makes it a practical choice when building a flame test kit for school use; it comes as a 500 gm pack with its MSDS. It is supplied by Jain Scientific Equipments Pvt Ltd (ScienceLab), Ambala, India.

| Product code | SCL-977/231 |
| Supplied by | Jain Scientific Equipments Pvt Ltd (ScienceLab), Ambala, India |
What Is Strontium Bromide Used For?
For the flame test, a clean wire loop is moistened with concentrated hydrochloric acid, dipped into a few crystals and held at the edge of a non-luminous Bunsen flame, where strontium gives a persistent crimson colour. Placing it beside lithium (carmine) and calcium (brick red) salts shows students how carefully they must look to tell similar reds apart. Clean the loop in acid and flame it between samples until it no longer colours the flame. Because the same salt also covers the halide tests, it earns a place in a salt analysis kit for school practicals.
For the anion, a solution acidified with dilute nitric acid gives a pale cream precipitate of silver bromide with silver nitrate, only partly soluble in concentrated ammonia. In the layer test, chlorine water displaces bromine, which colours an organic solvent layer orange-brown. Strontium bromide is an eye and skin irritant and absorbs moisture from the air, so wear eye protection near the flame, keep the container closed and store it in a dry cupboard.
Supplier
Jain Scientific Equipments Private Limited, known to customers by its ScienceLab brand, supplies Strontium Bromide from Ambala, Haryana, India. Inorganic salts for flame and anion tests are sourced for schools, colleges, universities and dealers, and can be combined with apparatus orders for delivery in India and international markets.

Frequently Asked Questions
What flame colour does Strontium Bromide give?
Strontium bromide gives a strong crimson red flame from the strontium ion. The shade is easiest to judge against lithium and calcium salts tested with the same clean loop and non-luminous Bunsen flame, since all three produce reds that students can confuse.
How is the bromide ion in Strontium Bromide confirmed?
The bromide in strontium bromide is confirmed with silver nitrate in dilute nitric acid, which gives a pale cream precipitate, and with the chlorine water layer test, in which released bromine colours an organic solvent layer orange-brown.
Why has the Strontium Bromide clumped in the bottle?
Strontium bromide is hygroscopic and picks up water vapour whenever the lid is left off. Clumping does not affect its use in qualitative tests, but the pack should be stored tightly closed in a dry cupboard to keep it free-flowing.
What safety information comes with Strontium Bromide?
Each pack of strontium bromide comes with an MSDS covering eye and skin irritation, first aid, storage and disposal. Eye protection is advisable during flame testing, and students should keep loose sleeves and hair away from the Bunsen flame.
What is the shelf life of Strontium Bromide?
No blanket shelf life is quoted for strontium bromide, because shelf life depends on the chemical, its grade and storage conditions. Ask us for the expiry date of the batch you are quoted, and keep the container sealed against moisture.

| Supplied by | Jain Scientific Equipments Pvt Ltd (ScienceLab), Ambala, India |
What Is 3% Hydrogen Peroxide Solution Used For?
The classic demonstration adds a small amount of manganese dioxide to the solution in a flask fitted with a delivery tube; the peroxide decomposes steadily, and the oxygen is collected over water in a gas jar using standard gas collection apparatus, then identified by relighting a glowing splint. Comparing the rate with and without the catalyst, or with different catalysts, turns the same set-up into a lesson on reaction rates.
Biology classes drop small pieces of fresh liver or potato into the solution to show catalase at work: vigorous frothing appears with fresh tissue but not with boiled tissue, illustrating enzyme denaturation. In analysis, the solution oxidises iodide in acid to iodine and iron(II) to iron(III). Hydrogen peroxide slowly decomposes, faster in light, heat or contact with metals, so store it closed in a cool, dark place, never pour unused portions back into the bottle, and wear eye protection even at this dilution.

Frequently Asked Questions
What does 3% w/v mean for Hydrogen Peroxide Soln. 3% w/v?
It means 3 g of hydrogen peroxide is dissolved in every hundred millilitres of solution. This dilute strength of Hydrogen Peroxide Soln. 3% w/v is chosen for classroom work because it releases oxygen at a steady, manageable rate with a catalyst.
Is 3% Hydrogen Peroxide strong enough to relight a glowing splint?
Yes. With manganese dioxide as catalyst, 3% hydrogen peroxide gives a steady stream of oxygen that can be collected over water in a gas jar and identified by relighting a glowing splint, the standard school test for the gas.
Why does Hydrogen Peroxide solution lose strength after opening?
Hydrogen peroxide naturally decomposes to water and oxygen, and light, warmth, dust and metal contamination speed this up. Keep the bottle capped in a cool, dark cupboard, never return unused solution to it, and check activity before an important demonstration.
What is the shelf life of Hydrogen Peroxide Soln. 3% w/v?
No fixed period is given, because shelf life depends on the chemical, its grade and storage conditions, and peroxide solutions are especially sensitive to heat and light. Ask us for the expiry date of the batch of Hydrogen Peroxide Soln. 3% w/v you are quoted.
Is 3% Hydrogen Peroxide safe for students to handle?
It is far milder than concentrated grades, but 3% hydrogen peroxide can still irritate eyes and skin. Students should wear goggles, avoid swallowing it and follow the MSDS supplied with each 500 ml pack for first aid, spills and disposal.

Strontium Sulphide
Strontium Sulphide (Product Code: SCL-981/233) is an analytical reagent grade inorganic compound used to demonstrate the sulphide anion test and the crimson strontium flame in college and senior-school salt analysis. Because one sample supports tests on both ions, teachers use it to trace a single salt through the whole analysis scheme; it comes as a 500 gm pack with its MSDS. It is supplied by Jain Scientific Equipments Pvt Ltd (ScienceLab), Ambala, India, a chemistry consumables supplier in India.

| Product code | SCL-981/233 |
| Supplied by | Jain Scientific Equipments Pvt Ltd (ScienceLab), Ambala, India |
What Is Strontium Sulphide Used For?
When dilute acid is added to a little of the solid, hydrogen sulphide is released and turns moist lead acetate paper black, confirming the sulphide anion. The resulting strontium solution then gives a crimson flame, a white precipitate of strontium carbonate with ammonium carbonate, and a white precipitate of strontium sulphate with sulphate ions, letting students trace one compound through both halves of a salt analysis scheme.
Because moisture and acids both liberate hydrogen sulphide, every acid test should be carried out inside a fume cupboard, a fixture most school labs in India now plan for wherever sulphides are handled. Keep the pack tightly sealed in a dry store away from acids and oxidisers, weigh portions quickly and never smell the gas directly. The reagent is intended for chemical tests; glow-in-the-dark behaviour depends on added activators and is not a listed property of this pack.
Supplier
Strontium Sulphide is sourced for customers by Jain Scientific Equipments Private Limited, which operates under the ScienceLab name in Ambala, Haryana, India. Reagents for qualitative inorganic analysis are supplied to schools, colleges, universities and distributors, and can be packed with glassware orders for India and international markets.

Frequently Asked Questions
Does this Strontium Sulphide glow in the dark?
Glow is not a listed property of this Strontium Sulphide analytical reagent pack; luminous grades rely on specific activator metals. If you need a phosphorescent material for a demonstration, contact us before ordering so we can confirm what is available.
Why does Strontium Sulphide smell of rotten eggs?
Moisture slowly reacts with strontium sulphide to release traces of hydrogen sulphide, which has the rotten-egg smell. A noticeable odour means the pack should be opened only in a fume cupboard and resealed tightly straight after weighing.
Which tests identify both ions in Strontium Sulphide?
For the sulphide, add dilute acid to strontium sulphide and hold moist lead acetate paper in the gas, which turns black. For strontium, use the crimson flame test and precipitation as the carbonate with ammonium carbonate or as the sulphate.
What is the shelf life of Strontium Sulphide?
Strontium sulphide has no fixed shelf life stated here, because shelf life depends on the chemical, its grade and storage conditions, and this compound reacts slowly with damp air. Ask us for the expiry date of the batch you are quoted.
What comes in a Strontium Sulphide pack?
Each Strontium Sulphide pack holds 500 gm of analytical reagent grade material and is supplied with an MSDS covering hazards, first aid, storage away from acids and safe disposal of sulphide waste.

What Is Dilute Sulphuric Acid Used For?
In redox titrations with potassium permanganate, whether against oxalic acid or ferrous ammonium sulphate (Mohr's salt), dilute sulphuric acid supplies the acidic medium. It is preferred because hydrochloric acid would itself be oxidised by permanganate and nitric acid is an oxidising agent in its own right, either of which would distort the titre. A measured portion is added to each flask before titrating.
It is also the first reagent reached for in any salt analysis kit for school practicals: warming a salt with dilute acid shows carbonate by effervescence that turns lime water milky, sulphide by gas that blackens lead acetate paper, sulphite by a pungent gas, nitrite by brown fumes and acetate by a vinegar smell. With granulated zinc it produces hydrogen that burns with a squeaky pop. Even dilute, the acid irritates eyes and skin, so goggles are essential; if further dilution is needed, always add acid slowly to water, never the reverse.

Frequently Asked Questions
What concentration is Sulphuric Acid Dilute?
The concentration of Sulphuric Acid Dilute is not stated in the current product listing. Please contact us with the strength your method requires, such as the normality used in your titration scheme, so we can confirm before you order.
Why use Sulphuric Acid Dilute rather than hydrochloric acid in permanganate titrations?
Because permanganate oxidises chloride ions, which would consume extra titrant and give a false result. Sulphate ions from dilute sulphuric acid are not oxidised, so the titre reflects only the oxalic acid or Mohr's salt being analysed.
Can Sulphuric Acid Dilute be used to make hydrogen in class?
Yes. Added to granulated zinc in a flask or boiling tube, dilute sulphuric acid releases hydrogen, which can be collected over water and tested with a lighted splint for the characteristic squeaky pop.

What Is Concentrated Sulphuric Acid Used For?
In the brown ring test, the concentrated acid is run slowly down the side of a tilted tube containing a nitrate solution and freshly made ferrous sulphate; a brown ring at the junction of the two layers confirms nitrate. Warming a dry salt with the acid reveals chloride by fumes that form white clouds with ammonia, bromide by reddish-brown vapour and iodide by violet vapour. Organic practicals use a few drops to catalyse the esterification of ethanol with acetic acid, recognised by its fruity smell, and to form the violet ring of Molisch's test for carbohydrates.
Mixing with water releases a great deal of heat, so dilution must always be done by adding acid slowly to water with stirring, never the other way round. Heated tests and sugar-charring demonstrations belong in a fume cupboard, and for school labs a face shield, acid-resistant gloves and a nearby eyewash are sensible minimums. Store the bottle in an acid cabinet, apart from bases, metal powders, oxidisers and organic materials.

Frequently Asked Questions
How should Sulphuric Acid Concentrated be diluted?
Pour concentrated sulphuric acid slowly into a larger volume of water in heat-resistant glassware, stirring constantly and letting it cool. Adding water to the acid instead can cause violent boiling and spattering, so never reverse the order.
Why must the Sulphuric Acid Concentrated bottle be kept tightly capped?
Because concentrated sulphuric acid absorbs water vapour from the air, which gradually dilutes it and can leave the outside of the bottle wet with acid. Close the cap immediately after each use and wipe the neck before storing.
Should students handle Sulphuric Acid Concentrated directly?
Only senior students under close supervision should handle concentrated sulphuric acid. For routine school tests such as anion analysis and hydrogen preparation, the separate Sulphuric Acid Dilute listing is the safer choice for student benches.
What protective equipment does Sulphuric Acid Concentrated require?
Handling concentrated sulphuric acid calls for splash goggles or a face shield, acid-resistant gloves and an apron, with an eyewash or running water within reach. The MSDS supplied with each 500 ml pack gives full guidance on first aid and spills.
What is the shelf life of Sulphuric Acid Concentrated?
No fixed shelf life is quoted, since shelf life depends on the chemical, its grade and storage conditions. For Sulphuric Acid Concentrated, ask us for the expiry date of the batch you are quoted, and keep the bottle sealed in an acid cabinet.
