Statement: The dissociation constant of ...

Statement: The dissociation constant of water at `60^(@)C is 10^(-13)`.
Explanation: The pH of water is `6.5` and that it behaves as acid at `60^(@)C`.

A

S is correct but E is wrong.

B

S is wrong but E is correc.

C

Both S and E are correct and E is correct explanation of S.

D

Both S and E are correct but E is correct explanation of S.

Text Solution

Verified by Experts

The correct Answer is:
A
`K_(w)=10^(-1) at 60^(@)C` , `:. pH = 6.5`,
but water is neutral because pH scale contracts to ` 0 to 13`.
