WebJun 19, 2024 · There is a big difference between phosphoric acid (H 3 PO 4) and phosphorous acid (H 3 PO 3 ). PO 3 will oxidize eventually or be converted by microorganisms to become PO 4. The point is that phosphoric acid is often used to make fertilizers in the form of a phosphate (a salt of phosphoric acid). WebSep 21, 2024 · Phosphonates and phosphonic acids are organophosphorus compounds containing C−PO (OH)2 or C−PO (OR)2 groups (where R = alkyl, aryl). Phosphonic acids, typically handled as salts, are generally nonvolatile solids that are poorly soluble in organic solvents, but soluble in water and common alcohols.
