If the pH of a solution of an alkali metal hydroxide is 13.6, the concentration of hydroxide is

A

Between 0.1 M and 1 M

B

More than 1 M

C

More than `0.001` M

D

`Between `0.01` M and 1 M

Text Solution

Verified by Experts

The correct Answer is:
A
`pH = 13.6`
`pOH = 14 - 13.6 = 0.4`
`[OH^(-)] = " Antilog " (-0.4) = 0.3979 ` . So the value of `[OH^(-)] ` between 0.1 M and 1 M .
