酸度系数 Acid dissociation constant(重定向自Base dissociation constant)
酸度系数(英语:Acid dissociation constant,又名酸解离常数),代号Ka,在化学及生物化学中,是指一个特定的平衡常数,以代表一种酸解离氢离子的能力。 该平衡状况是指由一种酸(HA)中,将氢离子(即一粒质子)转移至水(H2O)。水的浓度[H2O]是不会在系数中显示的。一种酸的pKa越大则酸性越弱,pKa越小则酸性越强(反过来说,Ka值越大,解离度高,酸性越强,Ka值越小,部份解离,酸性越弱)。pKa<0的酸在水中是强酸,介于0与4.0之间为中强酸,其他为弱酸。离解的化学反应(酸的电离反应通式为)为:

![]() ![]() ![]() ![]() An acid dissociation constant, Ka, (also known as acidity constant, or acid-ionization constant) is a quantitative measure of the strength of an acid in solution. It is the equilibrium constant for a chemical reaction known as dissociation in the context of acid–base reactions. In aqueous solution, the equilibrium of acid dissociation can be written symbolically as: |
