QUESTION 16

When zinc metal reacts with copper (II) sulfate solution the substance receiving electrons is:
Zn (s)
O Cu (s)
O zn 2+ (aq) in ZnSO4 (aq)
O Cu 2+ (aq) in CuSO4 (aq)

Answer 1

Cu 2+ (aq) in CuSO4 (aq)

Step-by-step explanation:

In the reaction between zinc metal and copper (II) sulfate solution, the zinc metal is oxidized and loses electrons to form zinc ions, Zn^2+, which go into the solution as zinc sulfate, ZnSO4. The copper (II) ions, Cu^2+, in copper (II) sulfate solution is reduced and gain the electrons that the zinc metal lost, forming solid copper metal, Cu(s).

So the substance receiving electrons in this reaction is the copper (II) ions, Cu^2+, in CuSO4 solution, which gets reduced to form copper metal.
