Answer 1

Answer:

The above reactions are not correct.

i.)

Correct Reaction:

• Zn + CuSO₄ ➝ ZnSO₄ + Cu

Reason:

• First we all Cu when reacts with ZnSO there will be no reaction because in displacement reaction more reactive element displaces less active element from it's salt solution.
• Here, we know that Cu ( copper metal ) is below in activity series then zinc so it cannot displace zinc from its salt solution to form the required compound.
• Now the correct reaction given where, zinc is more reactive element than copper so it displaces copper from its salt solution and forms zinc sulphate.

➤ Zinc reacts with copper sulphate to form zinc sulphate and copper element.

ii.)

Correct Question:

• Fe + CuSO₄ ➝ FeSO₄ + Cu

Reason:

• There is no such element as copper sulphite so iron reacts with copper sulphate only.
• When a few pieces of iron are dropped into a blue coloured copper sulphate solution the blue colour of solution fades and eventually turns into light green due to formation of ferrous sulphate and copper metal is left behind.
• As iron is more reactive than copper it displaces copper from its salt solution because we know that the more reactive elements displaces the less reactive element from its salt solution.

Answer 2

Answer:

The above reactions are not correct

The correct reactions are__________

1. Zn + CuSO4 => ZnSO4 + Cu

2. Fe + CuSO4 => FeSO4 + Cu
