Answer

The conversion of ferrous sulphate to ferric sulphate is an oxidation reaction.
When ferric ion is formed. from ferrous ion, the positive charge is increased by one unit. while this happens the rerrous ion loses one electron. A process in which a metal or its ion loses one or more electrons is called an oxidation.

& 2 FeSO _4 \rightarrow Fe _2\left( SO _4\right)_3 \\
& Fe _2+ SO _4^{2-} \rightarrow 2 Fe ^{3+}+ SO _4^{2-} \\
& \text { Net reaction : } \underset{\text { Ferrous }}{ Fe ^{2+}} \rightarrow \underset{\text { Ferric }}{ Fe ^{3+}}+ e ^{-}
\end{aligned}
