Question

Give reasons : Magnesium replace Copper from copper sulphate solution. (at least 2 reasons)​

Answer 1

Answer:

Mg+CuSO

4

⟶MgSO

4

+Cu

(Blue)

By addingMagnesium to CuSO

4

, it turns to MgSO

4

.

Because Mg is above Cu in reactivity series. So Mg displaces Cu in CuSO

4

. As reaction processes, CuSO

4

content decreases.

∴ Color blue fades.

Answer 2

Answer:

more reactive metal can displace a less reactive metal from its compounds . For example, magnesium is more reactive than copper. It displaces copper from copper sulfate solution :

Mg(s) + CuSO 4(aq) → MgSO 4(aq) + Cu(s)

In this displacement reaction .
