Question

When we put some crystals of potassium permanganate in a beaker containing water, we observe that after sometime whole water has turned pink. This is due to:
a) Boiling
b) Melting of potassium permanganate crystals
c) Sublimation of crystals
d) Diffusion​

Answer 1

Answer:

the answer is D

Explanation:

Answer 2

Answer:

The diffusion process is the reason for the pink color of the water. Option d) is correct.

Explanation:

• The chemical formula of potassium permanganate is $KMnO_{4}$.
• Potassium permanganate is soluble in water and the crystals are purple-black in color.
• When molecules move from the region of the higher concentration to the region of the lower concentration, the process is termed diffusion.

When the potassium permanganate crystals are put in water the crystals are transformed into small particles. These small particles of potassium permanganate are diffused in the water giving it a pink color.

Hence, the diffusion process is the reason for the pink color of the water. Option d) is correct.
