Answer 1

Answer #1

Answer: HPO42- is a Monoprotic Acid

Expalanation: Monoprotic acid is a acid which can donate only one proton to an aqueous solution.

of the given group of choices-

1) Na3PO4 is a salt and does not belong to monoprotic acid as does not contains protons.

2) H3PO4 is a triprotic acid it can donate its 3 protons to an aqueous solution.

3) H2PO4- is a diprotic acid it can donate its 2 protons to an aqueous solution.

4) HPO42- is a monoprotic acid it can donate its 1 proton to an aqueous solution.

5) PO43– does not caontains protons
