Soda water(Carbon dioxide + water) | Gaseous | _____ | _____ |
A mixture of alcohol and water | Liquid | _____ | _____ |
Is there any relation between the state of the solution and that of the solvent?


Take equal amounts of water in two glass tumblers. Add one or two crystals of potassium permanganate in the first tumbler and four or five crystals in the second and stir. Observe the difference in the colour of the solutions in the two tumblers. What is the reason for the difference in the colour?

Do different materials dissolve to the same extent in a given solvent?
