The reactants of two chemical equations are listed. Equation 1: CuSO4 and NaOh. Equation 2: Fe and CuSO4. Based on the type of reaction, which reaction cane be used to extract copper metal from copper sulfate solution?

Equation 2, because Fe is being more reactive, replaces Cu from CuSO4

Equation 2, because Fe is being more reactive, replaces S from CuSO4

Equation 1, because Na is being more reactive, exchanges position with Cu in CuSO4

Equation 1, because qNa is being more reactive, exchange position with S in CuSO4

Equation 2, because Fe is being more reactive, replaces Cu from CuSO₄.

Explanation:

Equation 1 is: CuSO₄ + 2NaOH → Na₂SO₄ + Cu (OH) ₂.

The reaction between CuSO₄ and NaOH will give Na₂SO₄ and Cu (OH) ₂ which is a precipitate "replacement reaction".

While, equation 2 is: CuSO₄ + Fe → Cu + FeSO₄.

The reaction between CuSO₄ and Fe will produce Cu and FeSO₄.

Thus, it is used to extract Cu because Fe is more reactive than Cu, so it can replace it in its salts and Cu can be extracted.

So, the right choice is: Equation 2, because Fe is being more reactive, replaces Cu from CuSO₄.
