Explanation:

Step1: Separate two colorless liquids

If they have different boiling - points, distillation can be used. Heat the mixture, the liquid with the lower boiling - point will vaporize first, then be condensed and collected.

Step2: Separate a nondissolving solid mixed with a liquid

Filtration is suitable. Pour the mixture through a filter paper. The liquid will pass through while the solid is retained on the filter paper.
