Details
Disodium hydrogen phosphate (Na2HPO4) is a sodium salt of Phosphoric Acid. DSP is a white powder that is highly hygroscopic and water soluble. Sodium phosphate dibasic is therefore used commercially as an anti-caking additive in powdered products. DSP is also known as disodium hydrogen orthophosphate, sodium hydrogen phosphate or sodium phosphate dibasic. Disodium Phosphate is commercially available in both the hydrated and Anhydrous forms. PH of disodium hydrogen phosphate water solution is beTween 8.0 and 11.0.
