(a) Interpretation: The method for separating a homogeneous solution of table salt and water into its components should be determined. Concept introduction: Two or more substances combined in such a way that the identity of each substance remains unchanged that is they do not react with each other is said to be a mixture. Mixtures are either heterogeneous or homogeneous. A mixture of two or more substances which results in single phase (homogeneous mixture), the substance present in greater amount is said to be solvent and the substance present in smaller amount is said to be solute in solution. A mixture which consists of visibly different phases or substances in the mixture is known as heterogeneous mixture.
