Description

General description

In aqueous solutions, phosphoric acid behaves as a triprotic acid. The triprotic acid has three ionizable hydrogen atoms, which are lost sequentially.

Sigma Life Science is committed to bringing you Greener Alternative Products, which adhere to one or more of The 12 Principles of Greener Chemistry. This product has been enhanced for energy efficiency. Find details here.

Application

Industrially, phosphoric acid may be used in fertilizers, detergents, pharmaceuticals, water softeners.

Phosphoric acid has been used as an acid solution for pH adjustment of the fermentation broth in a protocol for the acetone-butanol-ethanol (ABE) fermentation of sugars in a bioreactor.

Packaging

100, 500 mL in glass bottle

Packaged in clear glass bottles

Other Notes

Concentrated phosphoric acid is approx. 85% H3PO4 (aqueous).
