Trisodium phosphate 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). In these uses, all sodium phosphates may be collectively referred to as sodium phosphate

Trisodium phosphate (Na3PO4) and disodium phosphate (Na2HPO4) can both effectively produce alkalinity by hydrolysis in water: Na3PO4 + H2O Na2HPO4 + NaOH Na2HPO4 + 2 H2O NaH2PO4 + NaOH The important difference between this source of alkalinity and that produced by free caustic soda lies in the reversibility of the above reactions.

Hardness Phosphate Control 25 Kgs Industrial and

2019-7-5·Phosphate/pH relationship recommended to control boiler corrosion. Different forms of phosphate consume or add caustic as the phosphate shifts to the proper form. For example, addition of monosodium phosphate consumes caustic as it reacts with caustic to form disodium phosphate in the boiler water according to the following reaction:

The formulation utilizes hydroxide alkalinity, which acts on the calcium phosphate, as well as magnesium, to form fluid, non-adherent sludges. These sludges are then easily removed from the system by bottom blowdown.
