Question

aqueous solution of raw sugar,when passed over beds of animal charcoal, becomes colourless ,explain.​

Answer 1

Answer:

Since, the colouring substances are absorbed by the charcoal which is due to the process of adsorption, which states that the chemical species are adsorbed by the surfaces of the particles.

So, when the aqueous solution of raw sugar is passed over the animal charcoal then the charcoal adsorbs all the colouring material and hence becomes colourless.

Answer 2

Answer:

When Raw Sugar Solution is passed through animal charcoal, a clear sugar solution is formed.

Explanation:

Since, Animal Charcoal is a very good adsorbent it is hence used for the purification of Sugar solution by removing the dyes present in the sugar solution.

Where these dyes move? These dyes move on to the surface of the charcoal.

We all have watched this kind of example in our daily life..

Example: If a chalk is kept in an ink bottle for 30 to 40 sec then the chalk " adsorbs " the colour. Where as if it was kept for 10min then the chalk "absorbs" the colour.
