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
At this temperature pH of neutral solution will be `13.4 //2` i.e., 6.7 . Thus, pH greater than 6.7 at this temperature refers to basic solution.
