Work Step by Step
Salt is an ionic compound soluble in water, if water is added to the mixture, it will dissolve and the sand will remain as an insoluble residue. When filtration is done, the sand remains on the filter paper and the salt remains in the solution. By evaporating an aqueous salt solution at over 100 degrees Celsius, a solid salt residue can be obtained.
This procedure represents the separation of compounds based on differences in solubility in water.
