Because water can ionize to some extent, according to the given reaction.

Explanation:

$2 H_{2} O ⇌ H_{3} O^{+} + O H^{-}$ $2H_2O rightleftharpoons H_3O^+ + OH^-$

This is another equilibrium reaction; and is most commonly quoted for a temperature of $298$ $298$ $K$ $K$ .

At this temperature, $K_{a}$ $K_a$ $=$ $=$ $[H_{3} O^{+}] [O H^{-}]$ $[H_3O^+][OH^-]$ $=$ $=$ $10^{- 14}$ $10^(-14)$ . Would you expect $K_{a}$ $K_a$ to increase or decrease at temperatures $>$ $>$ $298 K$ $298K$ ? Why or why not?
