Question

(I) Adding a small amount of pink powdered Potassium permanganate to a beaker of water turns the entire solution in the beaker to pink.
(II) Particles of matter show the property of diffusion.

Identify the correct option out of the following.

• A. Both (I) and (II) are correct and (II) is the correct explanation of (I)
• B. Both (I) and (II) are correct but (II) is not the correct explanation of (I)
• C. (I) is incorrect and (II) is correct
• D. Both are incorrect

Answer 1

The correct option is A Both (I) and (II) are correct and (II) is the correct explanation of (I)

• When pink coloured Potassium permanganate is added to water, the colour of the entire solution becomes pink because the particles of Potassium permanganate intermix with particles of water due to the continuous motion of the particles.
• This process of intermixing of particles of different types of matter on their own is called diffusion.
