WitrynaPolyphosphates arise by polymerization of phosphoric acid derivatives. The process begins with two phosphate units coming together in a condensation reaction. 2 H(PO 4) 2− ⇌ (P 2 O 7) 4− + H 2 O. The condensation is shown as an equilibrium because the reverse reaction, hydrolysis, is also possible. Witryna11 lis 2015 · The usage ‘*ortho-phosphoric acid’ and the like has been deemed unnecessary and obsolete because there is no ‘other’ form of phosphoric acid that one could want to differ between.
