Question

In reaction of KMnO₄ and Mohr’s salt, FeSO₄ is oxidised to
(a) Fe²⁺ (b) Fe³⁺
(c) Fe (d) All of the

Answer 1

So the reaction between Mohr's salt and potassium permanganate is a redox reaction. In this redox reaction ferrous ion from Mohr's salt gets oxidised and pink coloured of manganese present in potassium permanganate which is in the +7 oxidation state gets reduced to colourless Mn2+ state.
