Question

Observations for estimation of water crystallization in mohar salt by titrating with kmno4

Answer 1

Explanation:

redox reaction

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.
