Used to separate the soluble solids from the solution ?
Answer
Evaporation
Evaporation is used to separate a soluble solid from a liquid. For example, copper sulfate is soluble in water – its crystals dissolve in water to form copper sulfate solution. During evaporation, the water evaporates away leaving solid copper sulfate crystals behind.

Preparation • If the sand has a lot of debris in it, use a strainer to strain out the large debris and purify the sand. • Place some salt and sand separately on a napkin and, using the magnifying glass, closely examine the salt and sand. What do you notice? How does the size, shape and color of the grains of sand compare with the grains of salt? • Be careful when using the stove and oven, and when handling the boiling water. An adult should help you with these steps.
