Which statements are true of solutions? They contain solutes and solvents. They always have only one solute per solvent. Their p
melamori03 [73]

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.
