At a certain temperature the value of `pK_(w)` is `13.4` and the measured `pH` of soln is `7`. The solution is

A

Acidic

B

Basic

C

Neutral

D

Unpredictable

Text Solution

Verified by Experts

The correct Answer is:
B

`pK_(w) = 13.4`.
If we calculated the `pH` of `H_(2)O` from the above value, it come to be `6.7`. (Since cone, of `H^(o+)` and `oversea(Theta)OH` is equal).
So new scale is made from `0` to `13.4`.

So, at `pH = 7`, Solution is basic.
