The pH of such formulations is generally adjusted by mixtures of various sodium phosphates, such as this salt. The sodium chloride equivalent value, or E-Value, is 0.49. It is soluble in 4.5 parts water. Removal of the hydrogen atoms as protons H+ turns a phosphoric acid into a phosphate anion. Partial removal yields various hydrogen phosphate anions. The anions of orthophosphoric acid H 3PO 4 are orthophosphate (commonly called simply "phosphate") PO 4, monohydrogen phosphate HPO 4, and dihydrogen phosphate H 2PO 4. cann construction \u0026 brickwork
