Perchloric acid is a stronger acid than sulphuric acid. – InterviewSolution

1.	Perchloric acid is a stronger acid than sulphuric acid.
Answer» Solution :The oxidation state of Cl in perchloric acid is +7 while that of S in sulphur acid is +6 Due to higher oxidation state and higher electronegativity of Cl, `ClO_(3)` part of `HClO_(4)` pulls the electrons of the O-H BOND more strongly and hence can break the O-H bond more easily to liberate a proton than `SO_(2)` partin `H_(2)SO_(4)`. Thus, perchloric acid is a stronger acid than sulphuric acid.
