The metal which can be used to obtain metallic copper from aqueous CuS – InterviewSolution

1.	The metal which can be used to obtain metallic copper from aqueous CuSO_(4) is :
Answer» Na Ag Hg Fe Solution :(d) SODIUM reacts with WATER violently. Both silver and mercury are weaker reducing agents than copper. Therefore, metal iron can reduce `Cu^(2+)` ions to Cu. `Fe(s)+CuSO_(4)(aq) to FeSO_(4)(aq)+Cu(s)`
