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 · n H 2 O , where n is 2, 7, 8, and 12.
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.
Disodium phosphate is a very selective reagent for magnesium ions and, in the presence of ammonium salts and ammonia, forms a white precipitate of ammonium magnesium phosphate. Mg 2+ + NH 3 + Na 2 HPO 4 → (NH 4)MgPO 4 + 2Na + Ca 2+ Ca 2+ forms a white precipitate with ammonium oxalate. Calcium oxalate is insoluble in water, but is soluble in ...
“Ozempic has the active ingredient semaglutide and inactive ingredients including disodium phosphate dihydrate, propylene glycol, phenol, and water for injection,” Dr. Jaisinghani says.
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 ...
Recent research reveals that caffeine has health benefits for most moderate coffee drinkers. Here are the pros and cons of drinking certain coffees, with expert insights and advice.
Disodium pyrophosphate or sodium acid pyrophosphate (SAPP) [1] is an inorganic compound with the chemical formula Na 2 H 2 P 2 O 7. It consists of sodium cations ( Na + ) and dihydrogen pyrophosphate anions ( H 2 P 2 O 2− 7 ).
