The OH^(-) ion concentration of a soluti...

The `OH^(-)` ion concentration of a solution is `3.2 xx 10^(-4) M`. find out the `H^(+)` ion concentration of the same solution is

A

`3xx10^(-6)M`

B

`6xx10^(-6)M`

C

`3.125xx10^(-11)M`

D

`2xx10^(-4)M`

Text Solution

Verified by Experts

The correct Answer is:
C
`K_(w)=[H^(+)](OH^(-)]`
`[OH^(-)]=3.2xx10^(-4)M, [H^(+)]=(1xx10^(-14))/(3.2xx10^(-4))`
`=0.3125xx10^(-10)=3.125xx10^(-11)`
