At certain temperature the `H^(+)` ions concentration of water is `4 xx 10^(-7) M` then the value of `K_(w)` at the same temperature is

A

`10^(-14)M^(2)`

B

`2.5xx10^(-13)M^(2)`

C

`1.6xx10^(-13)M^(2)`

D

`4xx10^(-7)M^(2)`

Text Solution

Verified by Experts

The correct Answer is:
C
`H_(2)OhArrH^(+)+OH^(-)`
`4xx10^(-7)4xx10^(-7)`
`K_(w)=4xx10^(-7)xx4xx10^(-7)=16xx10^(-14)=1.6xx10^(-13)`
