Equation 1: CuSO4 and NaOH
Equation 2: Fe and CuSO4
Based on the type of reaction, which reaction can be used to extract copper metal
from copper sulfate solution?
4
1)
Equation 1, because Na being more reactive, exchanges position with Cu in
CuSO4
7
2) Equation 2, because Fe being more reactive, replaces S from CuSO4
