Question

when copper. is put into ferrous sulphate what happens and y

Answer 1

when copper is put into ferrous sulphate no reaction takes place because according to the reactivity table of elements copper is less reactive than iron
therefore,copper cannot displace iron.

Answer 2

ANSWER:

When copper is put into ferrous sulphate, no reaction takes place between Copper (Cu) and Ferrous Sulphate $\bold{\left(\mathrm{FeSO}_{4}}\right).$

EXPLANATION:

• The electrode potential for Iron is 'negative' and for copper it is 'positive' and hence copper is less reactive when compared to iron according to metal reactivity series.
• As less reactive metals cannot displace the metals with higher reactivity, copper cannot displace the iron present in ferrous sulphate solution and thus no reaction takes place between Ferrous Sulphate $\left(\mathrm{FeSO}_{4}\right)$ and Copper(Cu).
