浓度的配比就是指溶液的稀释、加浓、浓缩、配制的问题;其实质就是只含一种溶质的两种溶液的混合的问题,因此采用统一方法求解就很有必要,可能性也是存在的。下面就比较典型的问题进行探讨。问题:含有浓度为a/100的溶液的重量是A,含有浓度为c/100的溶液的重量为C,两种溶液混合后的浓度为b/100其重量为B。为方便起见不妨设a>c,显然a>b>c,由题意得方程方程组(Ⅰ)是有关溶液浓度问题的共性,因而也是解决有关的几种问题的共同的工具。
The concentration ratio refers to the problem of dilution, enrichment, concentration, and formulation of the solution; the essence is the problem of the mixture of two solutions containing only one solute, so it is necessary to use a unified method to solve the problem, and the possibility exists. of. The following is a discussion of typical issues. Problem: The weight of the solution containing the a/100 concentration is A, the weight of the solution containing the c/100 concentration is C, the concentration of the two solutions after mixing is b/100 and their weight is B. For the sake of convenience, it may be desirable to set a>c, obviously a>b>c. The equation equation equation (I) is the commonality of the solution concentration problem, and thus is a common tool for solving several related problems.
