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

A

`HClO_(4) gt HCl gt HNO_(3)`

B

`HNO_(3) gt HClO_(4) gt HCl`

C

`HCl gt HClO_(4) gt HNO_(3)`

D

`HCl gt HClO_(4) gt HNO_(3)`

Text Solution

Verified by Experts

The correct Answer is:
A
In order to compare relative acid strength of strong acids likes `HClO_(4) and HCl `, we use glacial acetic acid as differentiating solvent. Conductometric measurements of their solutions in glacial acetic acid show that the strength of following mineral acids decreases in the order . `HClO_5 gt HBr gt H_2SO_4 gt HCl gt HNO_3 `
