Phosphorous acid strong or weak

WebThe phosphoric acid produced by either the wet or dry process is frequently heated, driving off water and producing a superphosphoric acid. The phosphate concentration in superphosphoric acid usually varies from 72 to 76 percent. ... Some soil testing laboratories analyze soils with both a weak Bray (P-1) and a strong Bray (P-2) procedure. Bray ... WebWhy phosphorus acid is a weak acid? H 3 PO 4 is considered a weak acid because it doesn’t dissociate completely in an aqueous solution to give H + ions. It means when H 3 PO 4 is dissolved in an aqueous solution then some moles of it remain bounded (undissociated) in solution and are not fully ionized to yield H + ions.
