Question

a dilute ferrous sulphate solution was gradually added to the beaker containing acidified permanganate solution the light purple colour of the solution fades and finally disappear​

Answer 1

Answer:

permanganate solution is usually purple in colour. ... Since Potassium permanganate (KMnO₄) is quite an unstable compound, it tends to decompose in the presence of Ferrous sulphate (FeSO₄). This changes the colour of the solution from purple to colourless.
