溶解度图表较直观形象地表现出不同温度下所对应的溶解度,且便于比较不同物质的溶解度变化情况,是数化结合的亮点.考点1图像例1(2011年肇庆)根据下图A、B、C三种固体的溶解度曲线回答:①要使C的饱和溶液成为不饱和溶液,可采用的一种方法是——.②将三种物质饱和溶液的温度分别从50℃降到20℃时,溶液中溶质的质量分数最大的是.分析C的溶解度随温度的升高而降
Solubility chart more intuitively shows the corresponding solubility at different temperatures, and easy to compare the solubility of different substances changes, is a combination of bright spots.Examination 1 image Example 1 (2011 Zhaoqing) According to the following figure A, B, Solubility Curve of Three Solids Answer: ① One of the methods that can be used to make the saturated solution of C into an unsaturated solution is -. ② When the temperature of the saturated solution of the three substances is reduced from 50 ° C to 20 ° C, respectively, The solute mass fraction in solution is the largest. The solubility of C decreases with increasing temperature
