·       Phosphoric acid is used mainly in fertilizers.

·       It is used as an external standard for phosphorus-31 Nuclear magnetic resonance (NMR)

·       It is used as an electrolyte in phosphoric acid fuel cells and as a catalyst in the hydration of alkenes to produce alcohols, predominantly ethanol.

·       It finds application as a buffer agent in biology and chemistry; as a solution for anodizing and as a cleaner by construction trades to remove mineral deposits, cementations smears and hard water stains.

·       It is also used as a pH adjuster in cosmetics and skin-care products and a dispersing agent in detergents and leather treatment.

·       It plays an important role in the preparation of albumin derivatives.

·       It is an important starting material used in the preparation of disodium hydrogen phosphate, disodium phosphate, calcium hydrogen phosphate and monohydrate phosphate.

·       It is widely used to remove rust in steel tools or surfaces by converting the rusted ion in to water soluble phosphate compound.
