Pure water is heated from $2 5^{\circ} C$ to $6 0^{\circ} C$ . Select the correct statement(s):

Answer:

A, C

Solution:

Ionisation of water is endothermic, so $K_{w}$ increases: (A) true.

$[H^{+}]$ and $[OH^{-}]$ rise equally, so water stays neutral: (C) true, (B) false.

$pH + pOH = p K_{w}$ , which falls below 14: (D) false.

Answer: (A), (C).
