Monocalcium phosphate is an inorganic compound with the chemical formula Ca(H 2 PO 4) 2 ("AMCP" or "CMP-A" for anhydrous monocalcium phosphate). It is commonly found as the monohydrate ("MCP" or "MCP-M"), Ca(H 2 PO 4) 2 ·H 2 O. Both salts are colourless solids. They are used mainly as superphosphate fertilizers and are also popular leavening ...
These materials contain Ca 2+ combined with the polyphosphates, such as P 2 O 4− 7 and triphosphate P 3 O 5− 10: Dicalcium diphosphate (CAS#7790-76-3]: Ca 2 P 2 O 7; Calcium triphosphate (CAS# 26158-70-3): Ca 5 (P 3 O 10) 2
These compounds contain a layer polymeric anion consisting of HPO 3 tetrahedra linked by hydrogen bonds. These layers are interleaved by layers of metal cations. [8] Organic esters of hydrogen phosphites are anions with the formula HP(O) 2 OR − (R = organic group). One commercial example is the fungicide fosetyl-Al with the formula [C 2 H 5 ...
hp(o) 2 (oh) − → hpo 2− 3 + h + pk a = 6.7 The conjugate base HP(O) 2 (OH) − is called hydrogen phosphite, and the second conjugate base, HPO 2− 3 , is the phosphite ion. [ 8 ] ( Note that the IUPAC recommendations are hydrogen phosphonate and phosphonate respectively).
The general formula of a phosphoric acid is H n+2−2x P n O 3n+1−x, where n is the number of phosphorus atoms and x is the number of fundamental cycles in the molecule's structure, between 0 and n + 2 / 2 . Pyrophosphate anion. Trimethyl orthophosphate.
P 4 + 4 OH − + 4 H 2 O → 4 H 2 PO − 2 + 2 H 2. Any phosphites produced in this step can be selectively precipitated out by treatment with calcium salts. The purified material is then treated with a strong, non-oxidizing acid (often sulfuric acid) to give the free hypophosphorous acid: H 2 PO − 2 + H + → H 3 PO 2. HPA is usually ...

The structures of CaP and sodium peroxide (Na 2 O 2) are very similar. [1] The solid is described as a salt: (Ca 2+) 2 P 2 4−, or Ca 2 P 2. Since the bonding is ionic, the diphosphide centers carry negative charge and are easily protonated. Upon hydrolysis this material releases diphosphine (P 2 H 4): [2] Ca 2 P 2 + 4 H 2 O → 2 Ca(OH) 2 + P ...
