At some high temperature the value of K(...

At some high temperature the value of `K_(w)` is equal to `10^(-12) M^(2)`. Calculate the `H^(+)` ion concentration of water at same temperature is

A

`10^(-12)M`

B

`10^(-8)M`

C

`10^(-7)M`

D

`10^(-6)M`

Text Solution

Verified by Experts

The correct Answer is:
D
`K_(w)=[H^(+)][O^(-)H],H_(2)OhArrH^(+)+OH^(-)`
`[H^(+)]=[OH^(-)]K_(w)=[H^(+)]^(2)[H^(+)]=10^(-6)M`
