Answer to Question #24669 in Physical Chemistry for Ahsan Shamim

Question

can we prepare high concentration solution from low concentration solution?

Answer 1

Yes,by evaporating ( type of vaporization of a liquid that only occurs on the surface of a liquid. The other type of vaporization is boiling, which, instead, occurs within the entire mass of the liquid). Low concentration solution will lose water under this condition (heating) and salt, that is present in solution will stay in it, so solution will become more concentrated.
