Strips of zinc, iron, magnesium and copper are taken in the test tubes \( A, B, C \) and \( D \) respectively. Same quantity of ferrous sulphate solution is added to these test tubes. In which test tubes chemical reaction will occur? Why? Write the chemical equations for the reactions taking place here.

Answer»

According to the metal reactivity series- zinc, magnesium metals are highly reactive metals and iron metal is also move reactive than copper metal.

Highly reactive metal can displace les reactive metals from their solutions.

Order of reactivity-

Mg > Zn > Fe > Cu

Therefore-

In test tube 'A & B' chemical reaction occurs-

In test tube -A

Zn(5) + FeSO4(aq) → Zn SO4(aq) + Fe(s)

In test tube - B

Mg(s) + FeSO4 (aq) → MgSO4(aq) + Fe(s)

In test tube - C & D

→ No chemical reactions.
