What Is Sodium Benzoate Used For?

A simple and satisfying practical is the liberation of benzoic acid: students dissolve sodium benzoate in water, add dilute hydrochloric acid, and watch white benzoic acid separate out because it is far less soluble than its salt. The solid is filtered, washed and can be recrystallised from hot water to show purification by crystallisation. In functional-group analysis, a neutral solution of the salt gives a buff-coloured precipitate with neutral ferric chloride, which is the classic test for the benzoate ion.

In food and pharmaceutics lessons, sodium benzoate is used to compare how preservatives slow spoilage in acidic juices or syrups, and pharmacy college labs use it when preparing preserved oral liquids. Weigh it with a clean dry spatula, keep the container closed because the powder can absorb moisture and cake, and avoid mixing it with strong acids unless the experiment calls for it. It pairs well with potassium metabisulphite for a two-preservative comparison.

What Is Sodium Bicarbonate Used For?

Younger classes add sodium bicarbonate to vinegar or dilute acetic acid in a flask and capture the carbon dioxide in a balloon stretched over the neck, then bubble the gas through lime water to see it turn milky. Older students heat the solid in a dry test tube to show thermal decomposition, and use a sodium bicarbonate solution as the standard test for carboxylic acids, which give brisk effervescence while phenols do not. The same reaction lies behind models of soda-acid fire extinguishers and explains how baking powder makes dough rise, and the reaction of baking soda with vinegar features in many STEM science kits in India.

Because it is only mildly alkaline, a saturated sodium bicarbonate solution is also kept near the acid shelf for neutralising small acid splashes on benches, after which the area is rinsed with water. Keep the pack sealed and dry, since damp powder cakes and slowly loses carbon dioxide. Although low in hazard, the dust can irritate eyes, so goggles are still sensible during heating experiments.

Supplier

Sodium Bicarbonate is supplied by Jain Scientific Equipments Private Limited, whose trading name is ScienceLab, from Ambala, Haryana, India.

Frequently Asked Questions

Who supplies Sodium Bicarbonate SCL-951/218?
Sodium Bicarbonate (SCL-951/218) is supplied by Jain Scientific Equipments Pvt Ltd, trading as ScienceLab, Ambala, Haryana, India. The company sources this analytical reagent grade salt in 500 gm packs with an MSDS and supplies schools and colleges in India and international markets.

How much Sodium Bicarbonate is in one pack?
Each pack contains 500 gm of analytical reagent grade Sodium Bicarbonate. A carbon dioxide demonstration or carboxylic acid test uses only a spatula-tip of solid or a few millilitres of solution, so one pack supports many classes through the school year.

Is Sodium Bicarbonate the same as washing soda?
No. Washing soda is sodium carbonate, a stronger base, while Sodium Bicarbonate is sodium hydrogen carbonate. Heating Sodium Bicarbonate in a dry test tube converts it into sodium carbonate, water and carbon dioxide, which makes a useful classroom demonstration.

Why is Sodium Bicarbonate used in the carboxylic acid test?
Sodium Bicarbonate is used because carboxylic acids are strong enough to release carbon dioxide from it, while phenols and alcohols are not. Brisk effervescence with a sodium bicarbonate solution therefore points to a carboxyl group in the unknown organic compound.

What is the shelf life of Sodium Bicarbonate?
Shelf life depends on the chemical, its grade and storage conditions; ask us for the expiry date of the batch you are quoted. Store Sodium Bicarbonate tightly closed in a dry place, since damp powder cakes and slowly loses carbon dioxide.

Can a school order Sodium Bicarbonate with its other lab supplies?
Yes. Sodium Bicarbonate can be added to one enquiry with your glassware, acids and other reagents, and we will send a combined quotation for delivery in India or international markets. Use the enquiry cart to collect the items before sending.

What Is Sodium Bisulphite Used For?

For the bisulphite test, students prepare a freshly saturated solution of the salt in water, add a few drops of the carbonyl compound and shake well; aldehydes such as benzaldehyde and methyl ketones such as acetone form a white crystalline addition product, often after cooling the tube in cold water. The test complements the DNP (dinitrophenylhydrazine) test, which detects the carbonyl group in general, and the Tollens and Fehling tests, which pick out aldehydes. At college level, the same addition reaction is used to separate an aldehyde from a mixture and recover it later by warming with dilute acid or alkali.

As a reducing agent, a dilute sodium bisulphite solution decolourises iodine, removes excess chlorine from water samples, and clears brown manganese dioxide stains from glassware after permanganate titrations. Solutions lose strength on standing, so make them up fresh. Contact with acids releases sulphur dioxide, so work in a ventilated area and keep acids apart on the shelf. It belongs with the carbonyl reagents in any organised set of school chemistry lab equipment in India.

Supplier

Sodium Bisulphite is supplied by Jain Scientific Equipments Private Limited, which does business as ScienceLab from Ambala, Haryana, India, and sends reagents to teaching and testing laboratories in India and international markets. Buyers completing vendor or import paperwork can record the supplying company's Importer-Exporter Code AAECJ8618A (DGFT) and GSTIN 06AAECJ8618A1ZT. The company profile page gives further background.

Frequently Asked Questions

Who supplies Sodium Bisulphite SCL-953/219?
Sodium Bisulphite (SCL-953/219) is supplied by Jain Scientific Equipments Pvt Ltd, trading as ScienceLab, Ambala, Haryana, India. The company sources this analytical reagent in 500 gm packs with an MSDS; its IEC and GSTIN for vendor records are listed in the Supplier section above.

Which compounds give a positive Sodium Bisulphite test?
Most aldehydes and methyl ketones, such as benzaldehyde and acetone, give a white crystalline addition product with saturated Sodium Bisulphite solution. Bulky ketones react poorly, so a negative bisulphite result does not rule out every carbonyl compound in an unknown sample.

Why must Sodium Bisulphite solution be freshly prepared?
Sodium Bisulphite solutions are slowly oxidised by air and lose sulphur dioxide on standing, which weakens the addition test. Prepare the saturated solution on the day of the practical and discard what is left rather than storing it for the next class.

How much Sodium Bisulphite does one pack contain?
Each pack contains 500 gm of solid Sodium Bisulphite of analytical reagent grade. Because the carbonyl test uses only a few millilitres of saturated solution per group, a single pack serves many practical sessions in a school or college laboratory.

What is the shelf life of Sodium Bisulphite?
Shelf life depends on the chemical, its grade and storage conditions; ask us for the expiry date of the batch you are quoted. Keep Sodium Bisulphite in a tightly closed container, dry and away from acids and oxidising agents; the MSDS supplied gives full storage advice.

Can Sodium Bisulphite remove permanganate stains from glassware?
Yes. A dilute, slightly acidified Sodium Bisulphite solution reduces the brown manganese dioxide deposits left after permanganate titrations so they can be rinsed away. Rinse the glassware thoroughly with water afterwards and work in a ventilated area, as some sulphur dioxide is released.

What Is Sodium Bromide Used For?

In anion analysis, a solution of sodium bromide acidified with dilute nitric acid gives a pale cream precipitate with silver nitrate, which students compare with the white chloride and yellow iodide precipitates and test for solubility in ammonia. For the layer test, chlorine water is added to the bromide solution with a little carbon tetrachloride or carbon disulphide and shaken; the organic layer turns orange-brown as bromine is set free. This one tube shows that chlorine is more reactive than bromine, and repeating it with an iodide completes the displacement series for the halogens.

The salt itself is easy to handle, but the tests produce bromine and use chlorinated solvents, so perform them in small quantities in a fume cupboard or well-ventilated room, and collect the organic layers for proper disposal. Keep the container tightly closed, as the crystals slowly draw in moisture. Sodium bromide is a sensible addition to any halide set where students must identify ions in unknown mixtures.

Supplier

Sodium Bromide is supplied by Jain Scientific Equipments Private Limited, known by its trading name ScienceLab and located in Ambala, Haryana, India. The company sources inorganic reagents such as this so that schools and colleges can order the halide salts, test reagents and apparatus for anion analysis from a single source, in India and international markets.

Product codeSCL-959/222
Supplied byJain Scientific Equipments Pvt Ltd (ScienceLab), Ambala, India

What Is Sodium Metal Used For?

In organic chemistry practicals, a small, freshly cut piece of sodium is heated with the test compound in an ignition tube until the tube glows; the hot tube is then plunged into distilled water in a china dish, crushed, and the filtered sodium fusion extract is divided for separate tests for nitrogen, sulphur and halogens. In inorganic lessons, a teacher may drop a very small piece into a large trough of water behind a safety screen so the class can watch it melt, dart across the surface and release hydrogen while the water turns alkaline with sodium hydroxide.

Because sodium reacts with air and moisture, it is conventionally kept fully covered by dry kerosene or liquid paraffin in a tightly closed container. Cut it on a dry glazed tile with a dry blade, move pieces only with forceps, and blot off the oil before use. Scraps must never go into sinks or waste bins; they are normally destroyed by slow addition to an alcohol such as isopropanol under supervision, as the MSDS describes. Institutions stocking school chemistry lab equipment in India usually keep this reagent in a locked, dry cabinet separate from acids and water-based solutions.

Supplier

Sodium Metal is supplied by Jain Scientific Equipments Private Limited, which trades under the ScienceLab name from Ambala, Haryana, India. The company sources hazardous reagents such as this one and supplies them, with their safety data sheets, to schools, colleges, research laboratories and distributors in India and international markets.

What Is Sodium Nitroprusside Used For?

In inorganic qualitative analysis, a few drops of nitroprusside solution added to an alkaline solution or sodium carbonate extract of a salt produce a short-lived violet colour when sulphide is present, which is why the reagent sits in almost every salt analysis kit for school and college practicals. In the organic laboratory the same reaction confirms sulphur in the sodium fusion (Lassaigne's) extract. Because the colour fades within moments, students should watch the tube as the drops go in rather than after shaking.

Biochemistry and life-science teaching labs use the reagent for ketone detection: Legal's test gives a red colour with acetone in alkaline solution, and Rothera's test produces a purple ring with acetone and acetoacetate after saturation with ammonium sulphate and layering with ammonia. Nitroprusside solutions are light-sensitive and slowly lose strength, so keep the container closed in a dark cupboard and run a known positive sample beside each set of unknowns.

Supplier

This reagent is supplied by Jain Scientific Equipments Private Limited, the Ambala, Haryana company that trades as ScienceLab. It sources qualitative analysis reagents for school, college and research laboratories and dispatches them with their safety data sheets within India and to international markets.

Sodium Oxalate

Product Code : SCL-967/226

Sodium Oxalate (Product Code: SCL-967/226) is the white sodium salt of oxalic acid, used as a weighable reference standard for potassium permanganate titrations in college, university and school laboratories. Analysts value it because it is anhydrous and takes up little moisture, and each 500 gm pack is analytical reagent grade with an MSDS.

Product codeSCL-967/226
Supplied byJain Scientific Equipments Pvt Ltd (ScienceLab), Ambala, India

What Is Sodium Oxalate Used For?

The classic application is the standardisation of potassium permanganate. A weighed, dried portion of sodium oxalate is dissolved in water in a conical flask, acidified with dilute sulphuric acid and warmed, then titrated with permanganate from a burette until a faint pink colour persists. Students notice that the first drops lose their colour slowly and later drops react almost at once, because the manganese(II) ions formed speed up the reaction, a useful live example of autocatalysis. This routine exercise makes the salt a sensible part of any titration kit for school and college laboratories in India.

In anion analysis, a neutral oxalate solution gives a white precipitate of calcium oxalate with calcium chloride that does not dissolve in acetic acid, and it decolourises warm acidified permanganate. Sodium oxalate is harmful if swallowed or absorbed through the skin, so weigh it with a spatula, wear gloves, keep it away from food areas and wash hands after use.

Frequently Asked Questions

Who supplies Sodium Oxalate SCL-967/226?
Sodium Oxalate (SCL-967/226) is supplied by Jain Scientific Equipments Pvt Ltd, trading as ScienceLab, Ambala, Haryana, India. The company sources this analytical reagent in 500 gm packs with an MSDS; its GSTIN and LEI for tender and vendor files appear in the Supplier section above.

Why was this product listed as Sodium Oxaolate?
The product was earlier listed as Sodium Oxaolate, a misspelling of Sodium Oxalate; the chemical and the product code SCL-967/226 are unchanged, and the page address still uses the old spelling. Quote the product code in your enquiry to avoid any confusion.

Why is Sodium Oxalate preferred for standardising permanganate?
Sodium Oxalate is preferred because permanganate solutions change strength on standing and must be checked against a stable reference. The salt is anhydrous and weighs accurately, so a dried portion titrated in warm acid solution gives a dependable reference titre.

Should Sodium Oxalate be dried before weighing?
For standard solutions, most laboratories dry Sodium Oxalate in an oven and cool it in a desiccator before weighing, which removes any surface moisture. For simple qualitative oxalate tests, the salt can be used straight from the pack.

What is the shelf life of Sodium Oxalate?
Shelf life depends on the chemical, its grade and storage conditions; ask us for the expiry date of the batch you are quoted. Keep the Sodium Oxalate lid tightly closed between uses so the salt stays dry for accurate weighing.

What safety information comes with Sodium Oxalate?
An MSDS is supplied with every pack of Sodium Oxalate. It covers the hazards of swallowing or skin contact, first aid, storage and disposal of oxalate waste; students should wear gloves and keep the salt away from food areas.

What do you need to prepare a Sodium Oxalate tender quotation?

Teachers use this row of test tubes to explain why metal ions are separated into groups in qualitative analysis. The same solution provides a reliable positive control for the violet sodium nitroprusside test and for blackening lead acetate paper.

Sodium sulphide is corrosive to skin and eyes, and any contact with acid releases toxic hydrogen sulphide gas, so every step that acidifies a sulphide solution belongs inside a chemical fume cupboard. The solid readily absorbs moisture and slowly yellows in air, so reclose the container straight after weighing and store it well away from acids. Wear gloves and eye protection, and dispose of sulphide residues as the MSDS directs rather than pouring them into an acidic sink.

Frequently Asked Questions

Who supplies Sodium Sulphide SCL-969/227?
Sodium Sulphide (SCL-969/227) is supplied by Jain Scientific Equipments Pvt Ltd, trading as ScienceLab, Ambala, Haryana, India. The company sources this analytical reagent in 500 gm packs, each with an MSDS, for schools, colleges and research laboratories in India and international markets.

Why does Sodium Sulphide turn yellow after opening?
Sodium Sulphide turns yellow because exposure to air and moisture slowly forms polysulphides on the surface. Keep the lid tightly closed straight after weighing, and for careful quantitative work use material from a freshly opened pack.

How should a Sodium Sulphide test solution be prepared?
Dissolve a small quantity of Sodium Sulphide in distilled water shortly before the practical. Sulphide solutions deteriorate on standing, so make only what the session needs, label the bottle clearly and never acidify it outside a fume cupboard.

What are the main hazards of Sodium Sulphide?
Sodium Sulphide is corrosive to skin and eyes and releases toxic hydrogen sulphide gas when it contacts acids. The MSDS supplied with the pack sets out protective equipment, first aid and spill handling; store it well away from acids.

What is the shelf life of Sodium Sulphide?
Shelf life depends on the chemical, its grade and storage conditions; ask us for the expiry date of the batch you are quoted. Each Sodium Sulphide pack holds 500 gm, so keep opened stock tightly closed and dry between sessions.
