用含少量铁的氧化物的氧化铜制取氯化铜晶体(CuCl₂xH₂O)。有如下操作：

已知：在pH为4～5时，Fe^3＋几乎完全水解而沉淀，而此时Cu^2＋却几乎不水解。

(1)溶液A中的金属离子有Fe^3＋、Fe^2＋、Cu^2＋。检验溶液A中Fe^2＋的最佳试剂为_____（填编号，下同）。

①KMnO₄  ②(NH₄)₂S       ③NaOH        ④ KSCN

(2)氧化剂可选用_________。①Cl₂ ②KMnO₄ ③HNO₃ ④H₂O₂

(3)要得到较纯的产品，试剂可选用_______________。①NaOH ②FeO ③CuO ④Cu₂(OH)₂CO₃

(4)从滤液经过结晶得到氯化铜晶体的方法是_____________（按实验先后顺序选填编号）。

①过滤 ②蒸发浓缩 ③蒸发至干 ④冷却

(5)欲测定溶液A中的Fe^2＋的浓度，实验前，首先要配制一定物质的量浓度的KMnO₄溶液250mL，配制时需要的仪器除天平、玻璃棒、烧杯、药匙、胶头滴管外，还需_________，下列滴定方式中，最合理的是___________（夹持部分略去）（填字母序号）。

(6)为了测定制得的氯化铜晶体（CuCl₂xH₂O）中的x值，某学生设计了两种实验方案：

方案一：称取mg晶体灼烧至质量不再减轻为止，冷却、称量所得无水CuCl₂的质量为n₁g

方案二：称取mg晶体溶于水，加入足量氢氧化钠溶液、过滤、沉淀洗涤后用小火加热至质量不再减轻为止，冷却，称量所得固体的质量为n₂g。

试评价上述两种实验方案：其中正确的方案是________，理由是___________，据此计算得x＝_________（用含m、n₁或n₂的代数式表示）。
