【设计实验】用一氧化碳还原纯净的氧化铁粉末，实验装置如下图。

【进行实验】该小组按上述实验设计，在一定温度下进行了实验，测得下列数据：

①反应前玻璃管和内盛氧化铁粉末的总质量66.0g（玻璃管的质量为60.0g）

②反应后玻璃管和内盛黑色固体的总质量65.8g（冷却到室温称量）

【分析与讨论】本实验中，玻璃管内固体粉末由红色全部变为黑色。小明同学认为该黑色固体全部是铁，但小华同学提出了质疑，于是大家提出查阅资料。

【查阅资料】

① C O还原Fe₂O₃的固体产物的成分与反应温度、反应时间等因素有关

② CO还原Fe₂O₃的实验过程中固体产物可能有Fe₃ O₄、FeO、Fe

③ NaOH溶液与石灰水相似，能吸收CO₂，但不变浑浊
