(5)降温结晶
【详解】（1）由图1可知，t1℃时，丙的溶解度最大，故填：丙；
（2）由图1可知，t2℃甲物质的溶解度为60g，说明该温度下，100g水中最多能够溶解60g甲，50g水中最多能够溶解30g甲，则溶液的质量为50g+30g=80g，故填：80；
（3）由图1可知，甲、乙两物质溶解度随温度降低而降低，从t2℃降低到t1℃，会有固体析出，形成t1℃的饱和溶液，t1℃时，溶解度：乙>甲，则所得溶液的溶质质量分数的大小关系为乙>甲；丙溶解度随温度降低而升高，降温过程中，丙从饱和变成不饱和，溶液组成不变，溶质质量分数不变，所以降温后丙的溶质质量分数最小，故填：乙>甲>丙；
（4）由图1可知，丙的溶解度随温度的升高而降低。则丙物质的饱和溶液有晶体析出，说明温度升高，丙溶解度下降导致晶体析出；
A、氯化钠溶于水温度几乎不变，故A不符合题意；
B、氢氧化钠溶于水温度升高，故B符合题意；


（1）预测Al能和溶液反应，理由是______。
【进行实验】将一端缠绕的铝丝浸入溶液（如图），观察现象。
（2）铝丝表面未出现红色物质，原因是______。
【实验改进】用砂纸将铝丝表面打磨光亮，将其浸入溶液，观察现象
（3）填写实验报告单：
序号 实验现象 结论与解释
① 铝丝表面有少量气泡；铝丝周围出现蓝绿色物质 溶液显弱酸性，与Al反应产生的气体是______；蓝绿色物质成分待探究
