Question

ii) A student gradually adds dilute ferrous
sulphate solution to a conical flask containing
acidified potassium permanganate solution.
The light purple colour of the solution fades
and finally, it becomes colourless. Which of
the following is correct regarding the above
observation?
(a) Potassium permanganate oxidises ferrous
sulphate. (b) Potassium permanganate reduces
ferrous sulphate. (c) Ferrous sulphate oxidises
potassium permanganate. (d) Potassium
permanganate is an unstable compound and
undergoes decomposition to form a colourless
compound​

Answer 1

option a.

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.

Answer 2

Answer:

this is answer is not correct wrong answer:

ans:- option d) potassium permanganate is unstable compound and undergoes decomposition to from a colourless compound.

this is correct answer
