Question #aa61d

$2 {H}_{2} O \left(l\right) r i g h t \le f t h a r p \infty n s {H}_{3} {O}^{+} + H {O}^{-}$ ${K}_{a} = {10}^{-} 14$
At standard (and higher) temperatures, the ${K}_{a}$ value is quite small. The result is that water is a poor conductor because of the absence of species that can carry a charge.
