In an aqueous solution $\begin{aligned} & {\left[\mathrm{H}^{+}ight] 	imes\left[\mathrm{OH}^{-}ight]=10^{-14}} \ & {\left[\mathrm{H}^{+}ight]=\frac{10^{-14}}{\left[\mathrm{OH}^{-}ight]}} \ & =\frac{10^{-14}}{1 	imes 10^{-12}}=10^{-2} 	ext { or } 0.01 \mathrm{~mol} \mathrm{dm}^{-3} \end{aligned}$
