WebFor the reaction of phosphorous acid ($\ce{H3PO3}$) and potassium hydroxide ($\ce{KOH}$), write (a) the balanced molecular equation and (b) the net ionic equation. Write the balanced equation for the reaction whose equilibrium constant is the Kb for the dihydrogen phosphate ion. Aysce said: Alright, phosphoric acid is H3PO4. WebH3PO4+NaOH=NaH2PO4+H2O net ionic equation. H3PO4 dissociates into 3 hydrogen ions and 1 phosphate ion due to its weak acidic properties. On the other hand, NaOH dissociates into Na+ and OH- in a single response. This reaction results in a net ionic reaction where there is single hydrogen and hydroxyl ion.
