Which of the following expression is wrong?

A

`[H^(o+)] = [overset(Theta)OH] = 10^(-7)` for a neutral solution at all temperatures.

B

`[H^(o+)] lt sqrt(K_(w))` and `[overset(Theta)OH] gt sqrt(K_(w))` for basic solution

C

`[H^(o+)] = [overset(Theta)OH] = sqrt(K_(w))` for a neutral solution

D

`[H^(o+)] gt sqrt(K_(w))` and `[overset(Theta)OH] lt sqrt(K_(w))` for an acidic solution

Text Solution

Verified by Experts

The correct Answer is:
A
Statement (a) is wrong since it is not valid all temperature.
