How does solubility help in the separation of substances?

Solubility helps in separation by taking advantage of whether a substance can dissolve in a particular liquid or not. When one component of a mixture is soluble and the other is not, they can be separated easily.

For example, in a mixture of sand and salt, salt dissolves in water while sand does not. The sand can be removed by filtration, and then the salt can be recovered from the solution by evaporation.

This property is also useful when separating different dissolved substances by choosing suitable solvents. It allows us to isolate specific components without affecting others.

In simple terms, solubility makes separation easier by allowing one substance to dissolve while leaving the other behind, which can then be removed using appropriate methods.
