Question

Solutions of Zinc Sulphate, Aluminium sulphate are reacted with the given metals (zinc, Aluminium and Copper respectively) In which cases will you find displacement reaction taking place.(any four)​

Answer 1

Answer:

Aluminium has the ability to displace zinc, iron, copper from their respective salt solutions and therefore is more reactive than them.

Reactions:

2Al(s) + 3ZnSO4(aq) –→ Al2(SO4)3 3Zn(s)

2Al(s) + 3FeSO4(aq) –→ Al2(SO4)3 3Fe(s)

2Al(s) + 3CuSO4(aq) –→ Al2(SO4)3 3Cu(s)

Zinc has the ability to displace iron, copper from their respective salt solutions and therefore is more reactive than them.

Reactions:

Zn(s) + CuSO4(aq) –→ ZnSO4 (aq) + Cu(s)

Zn(s) + FeSO4(aq) –→ ZnSO4 (aq) + Fe(s)

Zn(s) + Al2(SO4)3(aq) –→ no reaction

Zn(s) + ZnSO4(aq) –→ no reaction

Iron has the ability to displace copper from its salt solution and therefore is more reactive when compared to Cu.
