Which one of the following is not a monoprotic acid?
Nitric acid |
||
Chloric acid |
||
hydrobromic acid |
||
Hydrofluoric acid |
||
Sulfuric acid |
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 |
