问答题

小明在做某次实验时，发现一瓶瓶口敞开不知多久的氢氧化钠溶液(下称试液)。联想到药品保存注意事项，小明利用提供的试剂(CaCl2溶液、盐酸、CaCO3固体、酚酞)对试液是否变质展开了探究。  

他首先的猜想是：试液没有变质，溶液的溶质还是NaOH。

实验方案是：取少量试液加入试管，滴入酚酞，观察到试液变红。由此得出的结论是原试液没有变质，还是NaOH。

(1)小明反思上述实验方案，觉得不够完善，理由是____________________________。

(2)完善实验方案后，他从提供的试剂中选取一种试剂进行实验发现原试液确已变质。请你写出他这次实验的操作、现象____________________________________________
