Question

Write the chemical reaction that takes place.

✓

Answer

Zinc $(Zn)$ is more reactive than iron $(Fe).$
Hence, when it is added to iron $(II)$ sulphate, it displaces the iron metal.
As a result, the colour of the solution fades from green to colourless due to formation of zinc sulphate, and the grayish black coloured iron metal gets displaced.
$\mathrm{Zn}(\mathrm{s})+\mathrm{FeSO}_4(\mathrm{aq}) \rightarrow \mathrm{ZnSO}_4(\mathrm{aq})+\mathrm{Fe}(\mathrm{s})$
