用C语言解决溶液体系pH值的计算

pH Account with Language C

确定溶液pH值是化学反应中比较重要的环节,而手工计算溶液的pH值是一个非常烦琐的过程,且极易出错。本文详细介绍如何利用计算机编写C语言程序来解决此类问题,求算时只需要按提示输入溶液的分析浓度及各级电离常数,程序将自动算出溶液的氢离子浓度和pH值,速度快且精确度高。

Making sure pH indicator in solution is more important tache in chemical reaction. For example, in the process of titra-tion of using EDTA, the pH indicator in solution is one of very important data it not only influences the choice of indicator, but also influences the precision of titration. But handworked counting pH indicator of solution is a very complex process. And easily makes mistakes. Because it involves many data in the solution of weak acid and weak alkali only can use stepwise approaching means. So handworked counting becomes very complex. This essay will detail introduce how to solve those problems by use computer' s language C. When counting only need according to cue to an analysis of consistence of solution and all levels of constant of ionization process will self-motion cipher out consistence of hydrogen and pH indicator of solution pace is quickly and precision is very exact.
