WebMar 7, 2016 · As Prem so ably explained pH will determine the solubility of Phosphates and this is optimized at between pH 6 to 7. In addition the use of humic materials can be useful for Phosphate... The simplest and most commonly encountered of the phosphoric acids is orthophosphoric acid, H3PO4. Indeed, the term phosphoric acid often means this compound specifically (and this is also the current IUPAC nomenclature). Two or more orthophosphoric acid molecules can be joined by condensation into larger molecules by elimination of water. Condensation of a few units yields th…
