右图是甲、乙两物质溶解度曲线,下列有关说法错误的是(  )

A.60℃时甲、乙溶解度相等

B.80℃时甲物质的溶解度大于乙物质的溶解度

C.60℃时乙物质的饱和溶液中最多含有乙物质30g

D.80℃时甲的饱和溶液降温到60℃时,仍为饱和溶液

答案

由于甲乙两物质溶解度在60℃有交点,且甲的溶解度随温度升高而增大,乙的溶解度随温度的升高而降低.

A、60℃时,甲乙两物质的溶解度交于一点,说明两物质在该温度下溶解度相等.正确.

B、从图中可以看出,80℃时甲的溶解度明显大于乙的溶解度.正确.

C、60℃,乙物质的溶解度是30g,但是由于溶液质量是未知的,所以无从判断溶质的质量.错误.

D、80℃时甲的饱和溶液降温,由于60℃的溶解度小于80℃的,所以溶液依旧是饱和的.正确.

故选C.
