Q. Statement 1 : The dissociation constant of water at $60^{\circ} C$ is $10^{-13}$
Statement 2 : The pH of water is $6.5$ and that it behaves as acid at $60^{\circ} C$

Equilibrium

Solution:

$K_w=10^{-13}$ at $60^{\circ} C \therefore pH =6.5$; but water is neutral because pH scale contracts to $0$ to $13$
