Monosodium phosphate which is also known as anhydrous monobasic sodium phosphate and sodium di-hydrogen phosphate, is a compound of di-hydrogen phosphate and sodium. One among plenty of sodium phosphates used very commonly as an industrial chemical. It exists as an anhydrous salt, as well as mono- and dehydrates. The salt is obtained by partial neutralization of phosphoric acid and its reaction with Caustic Soda until the desired PH is obtained.

Di-Potassium phosphate is formed when two equivalents of potassium react with phosphoric acid until the desired PH is obtained. Solution is then further dried to get fine quality white powder. Di-Potassium phosphate also known as potassium hydrogen orthophosphate and potassium phosphate dibasic, is a highly water-soluble salt which is often used as a fertilizer, food additive and buffering agent. It is a common source of phosphorus and potassium.
