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)`

Which of the following strongest acid in the following?A. `HCIO_(3)`B.

1.	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)`
Answer» Correct Answer - 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)`.
