Give appropriate reason for each of the following :
Perchloric acid is stronger than sulphuric acid.

Text Solution

Verified by Experts

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)` part in `H_(2)SO_(4)`. Thus, perchloric acid is a stronger acid than sulphuric acid.
