Web離子積常數（英語：Ion product constant）是化學平衡常數的一種形式，多用於純液體和難溶電解質的電離。 假設以下的電離方程式： R ⇌ nMm++ mNn- 其中R為溶質，Mm+和Nn-分別為電離出來的陽離子和陰離子，令其離子積為K，則K可表示為： K=[Mm+]n⋅[Nn−]m{\displaystyle K=[M^{m+}]^{n}\cdot [N^{n-}]^{m}} 與一般的平衡常數表達 … WebWrite the expression for the ion product constant for water, Kw. Write a chemical equation that illustrates the autoionization of water. Deuterium oxide 1D2O, where D is deuterium, the hydrogen-2 isotope) has an ion-product constant, Kw, of 8.9 * 10-16 at 20 °C. Calculate 3D+4 and 3OD-4 for pure (neutral) D2O at this temperature.
