1 explain why the saturation temperature is the temperature at which the first crystals appear.

2 what would be the effect on the observed saturation temperture if some of the water were lost by evaporation? idscuss and the answer.

溶解度的问题:
1. 在饱和度的溶液里溶质结晶的快 物质溶解成离子存在溶液里 但离子间有间距.一旦这个间距达到饱和密度时物质便不再溶解.所以对饱和溶液降温就会出现结晶.

2.溶液中的水蒸发掉了，溶液的饱和度增大，就会出现结晶。
