在分析化学中,对数浓度图解法是一种处理酸碱平衡体系有关计算的有效方法。以质子条件(PBE)为基础处理酸碱平衡体系的常用方法有两种:代数法和对数浓度图解法。 用代数法解题时,首先需选适用的公式,这项手续很麻烦,在随后进行的运算中,往往需解高次方程,数学处理也很复杂,求解较为困难。如能配合对数浓度图解法求解,则十分方便,绘图也比较简单,从图中可判断主要和次要组分,忽略次要组分
In analytical chemistry, logarithmic concentration mapping is an effective method of dealing with acid-base equilibrium systems. There are two common methods to deal with acid-base equilibrium system based on proton condition (PBE): algebra method and logarithmic concentration method. Algebraic method to solve the problem, we must first select the appropriate formula, this procedure is very troublesome, in the subsequent operation, often need to solve high-order equations, mathematical processing is also very complicated, the solution is more difficult. As with the logarithmic concentration graphical solution, is very convenient, the drawing is relatively simple, can be judged from the main and minor components, ignoring the secondary component
