解离常数

在化学、生物化学及药理学中,解离常数英语:dissociation constantK_{d})是一种特定类型的平衡常数,用于衡量一较大物体与另一较小组分分开(解离)的倾向,也可以描述配合物解体成组分分子或盐分裂为其组分离子。解离常数是缔合常数的倒数。对于一些特定的盐,解离常数亦可被称为电离常数。

对于一般的反应:


\mathrm{A}_{x}\mathrm{B}_{y} \rightleftharpoons x\mathrm{A} + y\mathrm{B}

其中复合物\mathrm{A}_{x}\mathrm{B}_{y}分解为x份A亚单位及y份B亚单位,则解离常数被定义为:


K_{d} = \frac{[A]^x \times [B]^y}{[A_x B_y]}

其中[A]、[B]与[AxBy]分别指A、B与复合物AxBy的浓度。

英语百科

Dissociation constant 解离常数

In chemistry, biochemistry, and pharmacology, a dissociation constant (K_{d} ) is a specific type of equilibrium constant that measures the propensity of a larger object to separate (dissociate) reversibly into smaller components, as when a complex falls apart into its component molecules, or when a salt splits up into its component ions. The dissociation constant is the inverse of the association constant. In the special case of salts, the dissociation constant can also be called an ionization constant.
