Disodium phosphate (DSP), or disodium hydrogen phosphate, or sodium phosphate dibasic, is an inorganic compound with the chemical formula Na 2 H P O 4. It is one of several sodium phosphates. The salt is known in anhydrous form as well as hydrates Na 2 HPO 4 ·nH 2 O, where n is 2, 7, 8, and 12. All are water-soluble white powders. The ...
A sodium phosphate is a generic variety of salts of sodium (Na +) and phosphate (PO 3− 4). Phosphate also forms families or condensed anions including di-, tri-, tetra-, and polyphosphates . Most of these salts are known in both anhydrous (water-free) and hydrated forms.
Trisodium phosphate was at one time extensively used in formulations for a variety of consumer-grade soaps and detergents, and the most common use for trisodium phosphate has been in cleaning agents. The pH of a 1% solution is 12 (i.e., very basic), and the solution is sufficiently alkaline to saponify grease and oils.
Phosphate-free detergents are sold as eco-friendly detergents. In the 21st century phosphates began to be reduced in percentage terms as an ingredient, leading to a New York Times report that said "low- or phosphate-free dishwasher detergents it tested, including those from environmentally friendly product lines that have been on the market for ...
Emits toxic fumes of phosphoxides and sodium oxide [8] ... Disodium phosphate, Na 2 HPO 4, is used in foods and monosodium phosphate, NaH 2 PO 4, is used in animal ...
Disodium pyrophosphate is also found in frozen hash browns and other potato products, where it is used to keep the color of the potatoes from darkening. [ 4 ] Disodium pyrophosphate can leave a slightly bitter aftertaste in some products, but "the SAPP taste can be masked by using sufficient baking soda and by adding a source of calcium ions ...
The process involves scission of a pyrophosphate bond, analogous to hydrolysis. SMFP can also be prepared by treating tetrasodium pyrophosphate or disodium phosphate with hydrogen fluoride. [2] In the laboratory, SMFP can be prepared by hydrolysis of difluorophosphate ions with dilute sodium hydroxide: PO 2 F 2 − + 2 NaOH → Na 2 PO 3 F + H ...
In chemistry, a phosphate is an anion, salt, functional group or ester derived from a phosphoric acid. It most commonly means orthophosphate, a derivative of orthophosphoric acid, a.k.a. phosphoric acid H 3 PO 4. The phosphate or orthophosphate ion [PO 4] 3− is derived from phosphoric acid by the removal of three protons H +.
