What is the best method of purifying drinking water?
The simplest method to purify water is probably boiling. You need to bring the water to a full, rolling boil for at least five minutes to be safe, with some experts recommending an even longer time. The downside to boiling your drinking water is that it removes the oxygen and the water ends up tasting flat.

Which method is used for purification of solid?
Crystallization
Crystallization is the most commonly used method for the process of purification of solids. In this method, impure substances are dissolved in a minimum amount of water and then filtered.
