Question

A more reactive metal can displace a less reactive metal from its salt solution

Answer 1

Answer: This is referred to as a metal displacement reaction. Explanation: In the electrochemical series, the metals which are at a higher position are more reactive and hence they displace less reactive metals( metals present near the bottom of the series) from their salts

Answer 2

Answer:

In a displacement reaction, a more reactive element removes a less reactive metal from its salt solution.

Explanation:

• According to the reactivity series, a more reactive element can displace a less reactive metal.
• Eg- Iron is a less reactive metal compared to zinc so it cannot remove zinc from its salt. While zinc is more reactive than iron and can easily displace it from its salt.

        $Zn + FeSO_{4}$ → $ZnSO_{4} + Fe$

• This is also an example of a redox reaction. The zinc is getting oxidized by losing electrons. The iron is getting reduced by gaining electrons.
