溶液在工农业生产中具有广泛的应用,根据需要人们对溶液的浓度采用了多种表示方法。稀溶液和浓溶液是人们通过自己的主观臆断,根据溶液中溶质和溶剂的相对多少进行定义,由于每个人的思维不一样,会产生很大的偏差。如甲认为A溶液是稀溶液,而乙认为A溶液是浓溶液。于是产生了用质量分数来客观的衡量溶液的浓稀程度的方法。在一定的外
The solution has a wide range of applications in industrial and agricultural production. According to the needs of people, a variety of expression methods are used for the concentration of the solution. Dilute solution and concentrated solution are defined by one’s own subjective judgment, according to the relative quantity of solute and solvent in solution, because each person’s thinking is not the same, it will produce a big deviation. If A thinks that A solution is a dilute solution, B thinks A solution is a concentrated solution. As a result, there has been a method of measuring the concentration of a solution objectively using the mass fraction. In a certain outside
