Question

Colour of iron sulphate solution does not change when copper turnings are dipped in dipped in it

Answer 1

displacement reaction does not take place because cu is less reactive than iron hence cu cannot displace iron from its salt solution

Answer 2

In simple words, the answer can be explained as :-

Copper is much less reactive than iron and hence is not in a position to displace iron from its aqueous solution. Basically there is no reaction taking place an the greenish iron sulphate solution remains.

The actual reason is, that copper has a higher reduction potential value than iron, hence copper can easily oxidise iron from 0 to a positive state.

The reaction that is supposed to take place here is, copper must reduce iron from +2 state to 0 state, but owing to a high reduction potential value than iron, it is unable to do so.

Hence there is no colour change observed.
