At some high temperature, K(w) of water ...

At some high temperature, `K_(w)` of water is `10^(-13)`. Then the `P^(H)` of the water at the same temperature is

A

`18.3`

B

`6.5`

C

`7.42`

D

6

Text Solution

Verified by Experts

The correct Answer is:
B
in water `p^(H)=(P^(kw))/(2) p^(H)=6.5 :. K_(w)=10^(-13)`
`[H^(+)]=10^(-65) " " :. P^(H)=6.5`
