Here are some properties of solutions: Homogeneous mixture: A solution is a homogeneous mixture of two or more substances. The particles of a solution are smaller than 10-9 meters in diameter and are too small to be seen by the naked eye. All components of a solution appear as a single phase. Colligative properties: These are the physical changes that occur when a solute is added to a solvent. Colligative properties are determined by the number of solute particles present, as well as the amount of solvent present. Solubility: This is the ability of a compound to dissolve in water. The...
