Can I get Na(s) using this reaction ?

Cu -> C ²+
Na+ -> Na

Yes Why ? No Why ?

Thank you very much
Greets.

Little hint: the reactivity of metals.

So the problem is : Cu doesn't react with Water ?
Copper has a lower activity than hydrogen and cannot replace it.?

compare reduction potential of the claimed elements Na Cu , to predict which species could be reduced and the one that can be oxidized

for this u should know about reduction -oxidation potential( electrochemical series).cu has low tendency to form ion.
cu+2 +2e-

cu
has +E value means equilibrium is towards right or low tendency to form ion or low reactivity.so less chance to react with cl
