Hydrofluoric acid

Sulfuric acid

Homework Answers

Answer #1

The Monoprotic Acid is a acid which can donate a single proton or hydrogen per molecule per an aqueous solution.

Nitric acid having formula HNO3 which can donate only one hydrogen so it is a Monoprotic Acid

Chloric acid HClO3 can donate only one hydrogen so it is a Monoprotic Acid

hydrobromic acid HBr can donate only one hydrogen so it is a Monoprotic Acid

Hydrofluoric acid HF can donate only one hydrogen so it is a Monoprotic Acid

Sulfuric acid H2SO4 can donate two protons on dissociation , so it is diprotic acid (it forms an ion on dissociation HSO3- on first dissociation and SO32- on second dissociation )

So answer is

Sulfuric acid H2SO4
