The pH of the solution produced by mixing equal volume of `2.0 xx 10^(-3) M HClO_(4)` and `1.0 xx 10^(-2) M KClO_(4)` is

`2.7`

`2.3`

`3.0`

`1.0`

Text Solution

Verified by Experts

The correct Answer is:

`H^(+)` contribution is by acid only as `KClO_(4)` is a salt of a strong acid and strong base which does not hydrolyse .
So , `pH = - log [2.0 xx 10^(-3)]`
` = 3 - log 2.0 = 3 - 0.3010 = 2.7`
