Answer (1 of 2): Basically it because of the structure.H3PO4 is O-H / O=P-O-H \ O-Hso each H+ can be removed to leave -Ominus.H3PO3 is O-H /O=P-H \ O-HPminus is just too unstable compared with Ominus. Although H3Bo3 contains 3 oh groups yet it is monobasic not tribasic bcoz boric acid do not exist as 3 oh groups in nature it exist in the molecular form in which ions of bo3 are joined together and no oh is free left with one thus it is a weak monobasic acid .. H3PO3 is phosphorous acid or orthophosphorous acid. When this reacts with NaOH one Na+ ions replaces the H in the only OH group and the other two H atoms (bonded directly to the P atom ) are not replaced. Please note your statement is not correct. Explain why phosphorous acid is not a tribasic acid like phosphoric acid through both acids contain three hydrogen in their molecules Thus, H3PO3 is dibasic as it has two P-OH bond. It is monobasic means it donates oe ions when dissolved in water though it contains two hydrogen atoms.. Join now. Which of the following is not a monobasic acid?
