Sodium Benzoate
Sodium Benzoate (Product Code: SCL-947/216) is the sodium salt of benzoic acid, a water-soluble compound used as a preservative and as a starting material for benzoic acid experiments in chemistry and food science laboratories. Organic chemistry, food science and pharmaceutics teaching labs use the 500 gm pack, which is analytical reagent grade and supplied with an MSDS. It is supplied by Jain Scientific Equipments Pvt Ltd (ScienceLab), Ambala, India, which serves institutions as one of the chemical laboratory equipment suppliers in India.

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.
Supplier
Sodium Benzoate reaches schools, colleges and pharmacy teaching labs through Jain Scientific Equipments Private Limited, which operates under the ScienceLab name from Ambala, Haryana, India. The company supplies reagents like this one so that chemicals, filter paper and glassware for a practical can be bought together, with delivery in India and international markets.

Frequently Asked Questions
Who supplies Sodium Benzoate SCL-947/216?
Sodium Benzoate (SCL-947/216) 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 and supplies chemistry, food science and pharmacy laboratories in India and international markets.
What is the pack size of Sodium Benzoate?
Sodium Benzoate is supplied in a 500 gm pack of analytical reagent grade powder. A benzoic acid preparation or benzoate ion test uses only a few grams, so one pack covers many student groups; order multiple packs for several laboratories.
How is benzoic acid obtained from Sodium Benzoate?
Benzoic acid is obtained by dissolving Sodium Benzoate in water and acidifying the solution with dilute hydrochloric acid. White benzoic acid precipitates because it is far less soluble than its salt, and it can then be filtered, washed and recrystallised from hot water.
How does the ferric chloride test work with Sodium Benzoate?
A neutral solution of Sodium Benzoate gives a buff-coloured precipitate with neutral ferric chloride, which is the classic test for the benzoate ion. The solution must be neutral, so avoid excess acid or alkali before adding the ferric chloride.
What is the shelf life of Sodium Benzoate?
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 Benzoate closed and dry, because the powder can absorb moisture and cake; the MSDS supplied covers safe handling.
Is this Sodium Benzoate suitable for adding to food?
This Sodium Benzoate is offered as an analytical reagent for laboratory work, such as preservative comparison studies. If you need a food- or pharmacopoeia-grade material for production, ask us through the contact page before ordering so we can advise.
