Steven never thought that the little cup would cause such a big problem. Peter became dependent on this cup because ever since he received the gift he would only drink water from the exact type of little blue cup. Over 12 years, Peter refused to drink w小丽在探究碱的化学性质时，将稀盐酸滴入到氢氧化钠溶液中，意外地看到有气泡产生，她认为氢氧化钠溶液已经变质了．用化学方程式表示氢氧化钠溶液变质的原因：　                                       　．【提出问题】变质后的氢氧化钠溶液中的溶质是什么？【猜想假设】小丽对变质后的氢氧化钠溶液中的溶质成分做出了两种猜想：猜想一：　        　；猜想二：　            　．【实验设计】为验证上述猜想哪个正确，小丽设计了如下方案：取少量氢氧化钠溶液样品于试管中，滴加几滴无色酚酞溶液，观察溶液颜色变化．小红认为小丽的实验方案不合理，理由是：　                                                        　．【实验与结论】小红另外设计并完成了实验，请你帮她填写下面的实验报告：实验步骤 实验现象 结论 步骤1：取少量氢氧化钠溶液样品于试管中，向其中滴加过量的　                                   　 　                  　 猜想一正确 步骤2：
