Question

Iron displaces copper from a solution of copper salt.The reaction is deemed as a redox reaction

Answer 1

Answer:

Explanation:

In this reaction iron loses two electron and is oxidized to Fe2+ . On the other hand Cu2+ gains two electrons and is reduced to copper. Thus the given reaction is a redox reaction

Answer 2

The reaction is a decomposition reaction as well as redox reaction as in this reaction, iron loses two electron and is oxidized to Fe2+ . On the other hand Cu2+ gains two electrons and is reduced to copper.

Whereas Iron(Fe) being more reactive than Copper(Cu) replaces copper from its salt solution. It cannot be termed as redox reaction as there is no transfer of electrons or oxygen atoms from either of the two elements, thus a decomposition reaction.

The reaction formed is,

Fe + CuSO⁴ ------> Fe²SO⁴ + Cu
