Answer 2

Zn and Cu Displacement Reactions with Iron

When investigating the ability of iron to displace metals zinc (Zn) and copper (Cu) from their salt solutions, we can observe displacement reactions. These reactions involve the transfer of electrons from one metal to another, resulting in the formation of new compounds.

The displacement reactions can be represented by the following equations:

1. Iron displacing zinc from zinc chloride solution: - Equation: Fe + ZnCl2 → FeCl2 + Zn - In this reaction, iron (Fe) displaces zinc (Zn) from its salt solution, zinc chloride (ZnCl2), forming iron chloride (FeCl2) and liberating zinc metal (Zn) [[1]].

2. Iron displacing copper from copper chloride solution: - Equation: Fe + CuCl2 → FeCl2 + Cu - In this reaction, iron (Fe) displaces copper (Cu) from its salt solution, copper chloride (CuCl2), forming iron chloride (FeCl2) and liberating copper metal (Cu) [[2]].

These displacement reactions occur because iron is more reactive than both zinc and copper. The reactivity series of metals determines their ability to displace other metals from their salt solutions. In this case, iron is higher in the reactivity series compared to zinc and copper, allowing it to displace them from their salt solutions.

It is important to note that the reactivity series of metals is a general trend and does not account for all possible reactions. Other factors, such as concentration, temperature, and the presence of catalysts, can also influence the outcome of displacement reactions.

I hope this explanation helps! Let me know if you have any further questions.
