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

`8.3`

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^(nH) = 6.5 :' K_(w) = 10^(-13)`
`[H^(+)] = 10^(-6.5)`
`:. P^(H) = 6.5`
