Phosphoric Acid
Phosphoric Acid (Product Code: SCI-441/185) is an analytical reagent grade mineral acid, also called orthophosphoric acid, used for polyprotic-acid titrations, phosphate buffer preparation and alcohol dehydration reactions in chemistry laboratories. It is supplied in a 250 ml bottle with an MSDS for schools, colleges and testing labs. It is supplied by Jain Scientific Equipments Pvt Ltd (ScienceLab), Ambala, India, a chemistry consumables supplier in India.

What Is Phosphoric Acid Used For?
Phosphoric acid gives up its three hydrogen ions in separate steps, so titrating it against sodium hydroxide while recording pH produces a curve with more than one end point — a clear illustration of a polyprotic acid for senior students. Partly neutralised, it forms the dihydrogen phosphate and hydrogen phosphate salts that make up phosphate buffers for biology and biochemistry practicals.
In organic chemistry it is a milder alternative to concentrated sulfuric acid as the catalyst for dehydrating alcohols, for example converting cyclohexanol to cyclohexene. Concentrated phosphoric acid is corrosive and viscous, so measure it slowly, wear gloves and goggles, and dilute it by adding acid to water. The MSDS supplied gives full storage and first-aid guidance.
Supplier
ScienceLab is how Jain Scientific Equipments Private Limited trades, and the company supplies phosphoric acid to laboratories together with the burettes, pH meters and glassware used in its practicals. A single enquiry covering reagents and apparatus returns one quotation, which is convenient when equipping a new laboratory. Institutions, dealers and importers in India and international markets are supplied. Read more on the ScienceLab profile.
Related Laboratory Equipment
Titration and buffer work with phosphoric acid uses the following.
- Sodium Hydroxide 500 g — titrant for the stepwise neutralisation of phosphoric acid.
- Digital pH Meter (Pen Type) — follows pH through the titration to reveal the separate end points.
- Burette — delivers the alkali in measured volumes.
- Sodium Dihydrogen Phosphate — a phosphate salt for buffer preparation.
- Acids Storage Cabinet — separate storage for corrosive mineral acids.

Frequently Asked Questions
What grade and size is this Phosphoric Acid?
This Phosphoric Acid (SCI-441/185) is analytical reagent grade and supplied in a 250 ml pack with an MSDS. The concentration is not stated in the listing, so ask us for the batch details if your method requires a particular strength.
Why is Phosphoric Acid used in titration practicals?
Phosphoric Acid is a triprotic acid that releases its hydrogen ions in stages, so a pH-monitored titration with sodium hydroxide shows more than one end point. This makes it a clear example for teaching polyprotic acids and the choice of indicators.
Can Phosphoric Acid be used to make buffers?
Yes. Phosphoric Acid can be partly neutralised with sodium hydroxide, or combined with phosphate salts such as sodium dihydrogen phosphate, to prepare phosphate buffers. These buffers are widely used in biology and biochemistry practicals where a stable pH is needed.
What is the shelf life of Phosphoric Acid?
Shelf life depends on the chemical, its grade and storage conditions, so we do not give a fixed period for Phosphoric Acid. Ask us for the expiry date of the batch you are quoted, and keep the bottle closed and upright in an acid store.
Who supplies Phosphoric Acid?
Phosphoric Acid (SCI-441/185) is supplied by Jain Scientific Equipments Pvt Ltd (ScienceLab), Ambala, Haryana, India, to schools, colleges, testing laboratories, dealers and importers in India and international markets.
How do I request a quotation for Phosphoric Acid?
To request a quotation for Phosphoric Acid, send the code SCI-441/185, the number of 250 ml bottles and your delivery location through the contact page or the enquiry cart. Related reagents and titration apparatus can be added to the same request.
