Our of `HClO_(4)` and `H_(2)SO_(4)`, which is a stronger acid in an aqueous solution

Out of HI and HCl, which is a stronger acid in aqueous solution ?

HClO_(4),HNO_(3) and HCl are all strong acids in aqueous solution.In glacial acetic acid medium, their acid strength is such that-

Statement-1 : When NaOH and H_(2)SO_(4) solutions are mixed, the resulting solution is always neutral Statement-2 : Both NaOH and H_(2)SO_(4) are strong electrolytes and are completely dissociated in aqueous solution.

Sodium salt of an organic acid 'X' produces effervesence with conc. H_(2)SO_(4) . X reacts with acidified aqueous CaCl_(2) solution to give a white precipitate which decolourises acidified KMnO_(4) . 'X' is

Explain, why HClO_4 is stronger acid than HClO_2

Assertion (A): H_(2)SO_(4) acts as a base in the presence of HCIO_(4) . Reason (R) : Perchloride acid is stronger acid than H_(2)SO_(4) .

Assertion (A): H_(2)SO_(4) acts as a base in the presence of HCIO_(4) . Reason (R) : Perchloride acid is stronger acid than H_(2)SO_(4) .

Assertion: HClO_(4) is a stronger acid than HClO_(3) . Reason: Oxidation state of Cl in HClO_(4) is +VII and in HClO_(3)+V .
