From Wikipedia, the free encyclopedia. Trisodium phosphate (TSP), is a cleaning agent, stain remover and degreaser, commonly used to prepare surfaces for painting.It can also be called trisodium orthophosphate and has the chemical formula Na3PO4. It is a highly water-soluble ionic salt.Solutions of it dissolved in water have an alkaline pH. It can also be found as a food additive; it is used as an acidity regulator (buffering agent), emulsifier, thickening agent, nutrition enlargement agent and sequestrant (metal-chelating agent).t is a highly water-soluble ionic salt.

The pKa of this is between 6.8-7.20. This compound can be made when phosphoric acid reacts with a sodium salt like sodium halide. Sodium phosphate dibasic. This compound is also known as disodium phosphate and has the molecular formula of Na 2 HPO 4. The molar mass of the compound is 142 g mol -1. When two sodium cations replace the hydrogen atoms in the phosphoric acid, sodium phosphate dibasic is obtained. So in the laboratory we can make this compound by reacting two equivalents of sodium hydroxide with one equivalent of phosphoric acid.
