Dipotassium Hydrogen Phosphate

Dipotassium Hydrogen Phosphate 

Dipotassium phosphate (K₂HPO₄) - also phosphoric acid, dipotassium salt; dipotassium hydrogen orthophosphate; 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.The pH of a dipotassium phosphate solution is almost neutral. It is formed by the stoichiometric neutralization of phosphoric acid with potassium hydroxide:
