Which statements are true of solutions? they contain solutes and solvents. they always have only one solute per solvent. their particles must be evenly distributed. they may contain solid, liquid, and gas simultaneously. they are always easy to distinguish from colloids. they are homogeneous matter. they are pure.

Explanation:

When two or more substances are mixed together in such a way that their particles are evenly distributed throughout the mixture then it is known as a solution.

Basically, a solution is a homogeneous mixture which can be present in any phase.

A solution contains both solute and solvent.

A colloid is defined as a substance in which solute particles are microscopically distributed throughout the solvent. In a colloid both solvent and solute are present in liquid phase.

Hence, a solution can be easily distinguished from colloids.

Therefore, we can conclude that following statements about solutions are true:

They contain solutes and solvents.Their particles must be evenly distributed.They may contain solid, liquid, and gas simultaneously.They are always easy to distinguish from colloids. They are homogeneous matter.
