Question

Statement 1: The dissociation constant of water at 60° C is 10-13 Statement 2: The pH of water is 6.5 and that it behaves as acid at 60° C (A) Statement 1 is True, Statement 2 is True; Statement 2 is correct explanation for Statement 1 (B) Statement 1 is True, Statement 2 is True; Statement 2 is not correct explanation for Statement 1 (C) Statement 1 is True, Statement 2 is False (D) Statement 1 is False, Statement 2 is True

Kw=10-13 at 60° C ∴ pH =6.5; but water is neutral because pH scale contracts to 0 to 13

Q. Statement 1 : The dissociation constant of water at $6 0^{\circ} C$ is $1 0^{- 13}$
Statement 2 : The pH of water is $6.5$ and that it behaves as acid at $6 0^{\circ} C$

Statement 1 is True, Statement 2 is True; Statement 2 is correct explanation for Statement 1

Statement 1 is True, Statement 2 is True; Statement 2 is not correct explanation for Statement 1

Statement 1 is True, Statement 2 is False

Statement 1 is False, Statement 2 is True

$K_{w} = 1 0^{- 13}$ at $6 0^{\circ} C ∴ p H = 6.5$ ; but water is neutral because pH scale contracts to $0$ to $13$

Q. Statement 1 : The dissociation constant of water at 60∘C is 10−13 Statement 2 : The pH of water is 6.5 and that it behaves as acid at 60∘C
