In a solution, the parts of the solution are mixed a) chemically. b) physically. c) only in water. d) by electronic means.

B) physically.

Explanation:

Solution is a homogeneous mixture of two or more components called as solute and solvent. Solute is the component which is present in smaller proportion and is solid for solid in liquid solution and solvent is the component which is present in larger proportion and is liquid for solid in liquid solution.

The solute and solvent do not combine chemically as in a mixture and thus are mixed only physically.Thus they can be separated by physical reactions.

Example: sugar dissolved in water can be separated by evaporation.
