ferrous sulpahte is added to acidic potassium permanganate and slowly the purple colour fades away ? why does this happen ??

answered-by-expert Expert Answer
When  ferrous sulpahte is added to acidic potassium permanganate slowly the purple colour fades away  because acidic potassium permanganate is an oxidising agent and it converts ferrous ions into ferric, while the purple permanganate changes to colourless manganese sulphate.
