Question

when ....gas is passed through potassium permanganate solution , which disappear violet colour​

Answer 1

Answer:

This makes the acidic potassium permanganate solution colourless. The formation of manganese sulphate (MnSO4) makes the solution colourless. -Thus, SO2 passed through an acidic potassium permanganate solution (purple in colour) turns it colourless. Thus, the correct option is (B) colourless.
