(D) In an aqueous solution at $298 \ K$:$[H^{+}] \times [OH^{-}] = K_w = 10^{-14} \ (mol \ dm^{-3})^2$Given $[OH^{-}] = 1 \times 10^{-12} \ mol \ dm^{-3}$$[H^{+}] = \frac{K_w}{[OH^{-}]}$$[H^{+}] = \frac{10^{-14}}{1 \times 10^{-12}} = 10^{-2} \ mol \ dm^{-3}$Therefore,$[H^{+}] = 0.01 \ mol \ dm^{-3}$.
