                                                           Buy Glasses to Read

       Tom had retired and lived by himself far away from town. He hardly ever left the village, but one day he

had to go into town to buy some things in the shops, and after he had bought them, he went into a restaurant and

sat down at a table by himself. When he looked around, he saw some old people put glasses on before reading

their newspapers, so after lunch he decided to go to a shop to buy himself a pair of glasses too. He walked along

the street, and soon found a shop.

       The man in the store made him try on many glasses, but Tom always said, "No, I can't read with these."

       The man became more and more puzzled, at last he said, "Excuse me, but can you read at all?"

       "No, of course I can't!" Tom said angrily. "If I was already able to read, do you think I would have come

here to buy glasses?"

草酸亚铁（FeC₂O₄•2H₂O）用作分析试剂及显影剂和新型电池材料磷酸亚铁锂的生产。已知：CO能与氯化钯（PdCl₂）溶液反应生成黑色的钯粉。回答下列问题：

I．兴趣小组对草酸亚铁的分解产物进行实验和探究。

（1）将气体产物依次通过A、澄清石灰水，B、氯化钯，观察到A中澄清石灰水都变浑浊，B中出现黑色物质生成，则上述现象说明气体产物中有                       。

（2）探究分解得到的固体产物中铁元素的存在形式。     

①提出假设

假设1：________； 假设2：FeO； 假设3：FeO和Fe混合物

②设计实验方案证明假设3。

限选试剂：  1.0 mol•L^－1盐酸、3% H₂O₂、0.1 mol•L^－1CuSO₄、20% KSCN、蒸馏水。

II．某草酸亚铁样品中含有少量草酸（为方便于计算，草酸亚铁中草酸根和草酸分子均用C₂O₄^2－代替）。现用滴定法测定该样品中FeC₂O₄的含量。滴定反应分别是：5Fe²⁺+MnO₄^－+8H⁺=5Fe³⁺ +Mn²⁺+4H₂O、5C₂O₄^2－+2MnO₄^－+16H⁺=10CO₂↑+2Mn²⁺+8H₂O。

（3）实验方案设计为：

①将准确称量的0.20g草酸亚铁样品置于250 mL锥形瓶内，加入适量2 mol/L的H₂SO₄溶液，使样品溶解，加热至70℃左右，立即用浓度为0.02000 mol/L的高锰酸钾标准溶液滴定至终点，记录数据。重复滴定2次。平均消耗V₁ mL。

②向上述滴定混合液中加入适量的Zn粉和过量的2 mol/L的H₂SO₄溶液，煮沸5～8min，用KSCN溶液在点滴板上检验点滴液，直至溶液不立刻变红。将滤液过滤至另一个锥形瓶中，继续用0.02000 mol/L的高锰酸钾标准溶液滴定至终点，记录数据。重复滴定2次。平均消耗V₂ mL。

③若某小组的一次测定数据记录如下： V₁= 18.90mL，V₂=6.20mL。根据数据计算0.20g样品中：n（Fe²⁺）=      ； n（C₂O₄^2－）=    ；FeC₂O₄的质量分数为               （精确到0.01%，FeC₂O₄的式量为144）
