Q. Statement 1 : $pH$ of water increases with an increase in temperature
Statement 2 : $K_w$ or water increases with increase in temperature

Equilibrium

Solution:

(A) is wrong. Dissociation of water is an endothermic reaction, so increasing $T$ will increase $\left[ H ^{\oplus}\right]$ and hence decrease in $pH$ (R) is correct
