在化学通报1953年8月号第321页上,曾有过关于强硷弱酸所成酸式盐水解後溶夜中氢离子浓度的计算方法的介绍,那篇介绍写得很详细,可是在计算的方法上仍觉太繁,而且其中出现了一个[OH~-]~2/[H~+]~2的数量,在意义上比较模糊,使学者不易看懂。这里再介绍另一种计算方法,可以得到与上述方法完全一致的结果,而省去好几个步骤,意义也容易弄清楚些。仍然以亚硫酸氢钠为例子,亚硫酸氢钠在水溶液中,有下面两种反应:
In the Chemical Bulletin, August, 1953, p. 321, there was an introduction to the calculation of the concentration of hydrogen ions in a solution of acid salts produced by the hydrolysis of acid and base weak acids. The introduction is very detailed, however, The method still feels too complicated, and there appears an amount of [OH ~ -] ~ 2 / [H ~ +] ~ 2 in the sense that it is fuzzy in the sense that it is not easily understood by scholars. Here to introduce another calculation method, you can get exactly the same method with the above results, eliminating the need for several steps, the meaning is easy to figure out. Still with sodium bisulfite as an example, sodium bisulfite in aqueous solution, the following two reactions:
