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.
[edit] Safety
As a food additive, Dipotassium phosphate is on the FDA's Generally recognized as safe, or GRAS, list of substances[1].
