Which of the following strongest acid in the following?

A

`HCIO_(3)`

B

`HCIO_(4)`

C

`H_(2)SO_(3)`

D

`H_(2)SO_(4)`

Text Solution

Verified by Experts

The correct Answer is:
B
Acidic order :
`overset(+7)(HClO_(4))gtoverset(+5)(HClO_(3))gtoverset(+3)(HClO_(2))gtoverset(+1)(HClO)`. The higher is the oxidation number of central non-metal in oxo acids, the more stronger is the acid. Also `HClO_(4)` is stronger acid than `H_(2)SO_(4)`.
