The conversion of ferrous sulphate to ferric sulphate is _______reaction.

Explanation

The conversion of ferrous sulphate to ferric sulphate is oxidation reaction. The net ionic reaction for the conversion of ferrous sulphate to ferric sulphate is:
`Fe^(2+)rarrFe^(3+)`
Here, the positive charge on Fe increases from +2 to +3. Therefore, it is an oxidation reaction.
