甲酸（HCOOH）是一种有刺激臭味的无色液体，有很强的腐蚀性。熔点8.4℃，沸点100.7℃，能与水、乙醇互溶，加热至160℃即分解成二氧化碳和氢气。

（1）实验室可用甲酸与浓硫酸共热制备一氧化碳：HCOOHH₂O+CO↑，实验的部分装置如下图所示。制备时先加热浓硫酸至80℃-90℃，再逐滴滴入甲酸。

①从下图挑选所需的仪器，画出Ⅰ中所缺的气体发生装置（添加必要的塞子、玻璃管、胶皮管，固定装置不用画），并标明容器中的试剂。

②装置Ⅱ的作用是_________________________。

（2）实验室可用甲酸制备甲酸铜。其方法是先用硫酸铜和碳酸氢钠作用制得碱式碳酸铜，然后再与甲酸斥制得四水甲酸铜[Cu(HCOO)₂·4H₂O]晶体。相关的化学方程式是：

2CuSO₄+4NaHCO₃==Cu(OH)₂·CuCO₃↓+3CO₂↑+2Na₂SO₄+H₂O

Cu(OH)₂·CuCO₃+4HCOOH+5H₂O==2Cu(HCOO)₂·4H₂O+CO₂↑

实验步骤如下：

Ⅰ、碱式碳酸铜的制备：

③步骤ⅰ是将一定量CuSO₄·5H₂O晶体和NaHCO₃固体一起放到研钵中研磨，其目的是_________________。

④步骤ⅱ是在搅拌下将固体混合物分多次缓慢加入热水中，反应温度控制在70℃-80℃，如果看到

______________（填写实验现象），说明温度过高。

Ⅱ、甲酸铜的制备： 将Cu(OH)₂·CuCO₃固体放入烧杯中，加入一定量热的蒸馏水，再逐滴加入甲酸至碱式碳酸铜恰好全部溶解，趁热过滤除去少量不溶性杂质。在通风橱中蒸发滤液至原体积的1/3时，冷却析出晶体，过滤，再用少量无水乙醇洗涤晶体2-3次，晾干，得到产品。

⑤“趁热过滤”中，必须“趁热”的原因是_______________________。

⑥用乙醇洗涤晶体的目的是____________________________。
