For this question basicity means the number of ordinarily replaceable O–H protons of an oxyacid, not the total H count. Count the dibasic acids among H₂CO₃, H₃PO₂, H₃PO₃, H₃PO₄, H₂CrO₄, HClO₃ and H₄P₂

Question

For this question basicity means the number of ordinarily replaceable O–H protons of an oxyacid, not the total H count. Count the dibasic acids among H₂CO₃, H₃PO₂, H₃PO₃, H₃PO₄, H₂CrO₄, HClO₃ and H₄P₂O₇. Do not count later condensation reactions.

TestHub · Accepted Answer

Carbonic, phosphorous and chromic acids are dibasic. Hypophosphorous acid is monobasic, phosphoric acid tribasic, chloric acid monobasic and pyrophosphoric acid tetrabasic. Thus 3 qualify.
