Even two or three crystals of potassium permanganate can impart colour to a very large volume of water. Which characteristic of particles of matter is illustrated by this observation ?

How is it possible for two small crystals of potassium permanganate to colour a large volume of water ?

When sugar is dissolved in water, there is no increase in the volume. Which characteristic of matter is illustrated by this observation ?

A piece of chalk can be broken into small particles by hammering but a piece of iron cannot be broken into small particles by hammering. Which characteristic of the particles of matter is illustrated by these observations ?

When we added crystals of potassium permanganate to the water, the colour of water will be changed. What will be the reason for it?

Why does a large volume of water get coloured due to a few crystals of potassium permanganate ?

An acid which can decolourise purple coloured potassium permanganate solution is :

Archit dropped a crystal of potassium permanganate into two beakers A and B containing hot water and cold water respectively. After keeping the beakers undisturbed for some time what did he observe and why ?

When a crystal of potassium peramagnate is placed in a beaker, its purple colour spreads throughout the water. What does this observation tell us about the nature of pottassium permanganate and water?
