Answer 1

Answer:

Chromatography–different colours from black ink.

Ethanol from ethanol and water–For example, liquid ethanol can be separated from a mixture of ethanol and water by fractional distillation. This method works because the liquids in the mixture have different boiling points. When the mixture is heated, one liquid evaporates before the other.

Salt from sea water–crystallization or evaporation
