Question

when a crystal of potassium permanganate is placed in a beaker, its purple colour spreads throughout the water. what does this observation tell us about the nature of potassium permanganate and water?​

Answer 1

Explanation:

The observation of purple colour spreads throughout the water is that the crystal of potassium permanganate is made up of many small particles and these particles of potassium permanganate occupy the spaces between them.

Answer 2

• The particles of KMn04 are purple while water particles are colourless.
• when KMn04 crystals is put in H20, KMn04 particles spreads from one another.
• Actually on dissolving KMn04 gets into the spaces of water making it purple.
