摘要
初中化学有关溶液溶质溶剂一类的计算题大致可分为溶液稀释型,溶液加浓型、溶液浓缩型和溶液配制型。这几种类型虽然各有自己的等量关系,但在解题时。只要把握住浓度百分比这一关键因素,则再难的题都迎刃而解。
There is a kind of exercises in Junior Maths.They can roughly be divided into some types:thinner solution., thicker solution , centrating solution and compounding solution. Though each kind has its. own relations of equality in solving the problems , if you grasp the key of the solute percent , any problems can be solved.
