22．(2009·山东)孔雀石主要含Cu₂(OH)₂CO₃，还含少量Fe、Si的化合物。实验室以孔雀石为原料制备CuSO₄·5H₂O及CaCO₃，步骤如下：

请回答下列问题：

(1)溶液A中的金属离子有Cu²⁺、Fe²⁺、Fe³⁺。从下列所给试剂中选择：实验步骤中试剂①为________(填代号)，检验溶液A中Fe³⁺的最佳试剂为________(填代号)。

a．KMnO₄　b．(NH₄)₂S　c．H₂O₂　d．KSCN

(2)由溶液C获得CuSO₄·5H₂O，需要经过加热蒸发、________、过滤等操作。除烧杯、漏斗外，过滤操作还用到另一玻璃仪器，该仪器在此操作中的主要作用是________________________________________________________________________。

(3)制备CaCO₃时，应向CaCl₂溶液中先通入(或先加入)________(填化学式)。若实验过程中有氨气逸出，应选用下列________装置回收(填代号)。

(4)欲测定溶液A中Fe²⁺的浓度，需要用容量瓶配制某标准溶液，定容时视线应________，直到________。用KMnO₄标准溶液滴定时应选用________(填“酸式”或“碱式”)滴定管。

解析：(1)试剂①的作用是将Fe²⁺氧化成Fe³⁺，同时不能引入新杂质，选c，检验Fe³⁺选d。(2)过滤前必须冷却结晶、过滤时必须用玻璃棒。(3)因CO₂在水中的溶解度小，应先加入NH₃·H₂O，为防倒吸宜用b吸收NH₃。(4)KMnO₄溶液会腐蚀橡皮，滴定时宜选用酸式滴定管。

答案：(1)c　d　(2)冷却结晶　引流　(3)NH₃·H₂O　b　(4)平视凹液面(或平视刻度线)　凹液面的最低点与刻度线相切　酸式
