 20 FACTS ABOUT SOLUTES AND SOLVENTS Here are 20 important facts about solutes and solvents: A solute is a substance that is dissolved in a solvent. The solvent is the dissolving medium. The solute and solvent can be in any state of matter: solid, liquid, or gas. The solute and solvent must be miscible, meaning they can mix together to form a solution. The solubility of a solute is the amount of solute that can dissolve in a solvent at a given temperature. The solubility of a solute can be affected by factors such as temperature, pressure, and the presence of other solutes. A solution can be saturated, unsaturated, or supersaturated. A saturated solution is a solution that contains the maximum amount of solute that can dissolve at a given temperature. An unsaturated solution is a solution that contains less solute than it can dissolve at a given temperature. A supersaturated solution is a solution that contains more solute than it can dissolve at a given temperature. The sol
