A solution is a homogeneous mixture of two or more substances. The term "solution" is most commonly used in the context of aqueous solutions, where the solvent is water and the solute is a chemical that is dissolved in the water. The solute is the substance that is being dissolved, while the solvent is the substance that is doing the dissolving. In a solution, the solute is dispersed evenly throughout the solvent. This means that, on a molecular level, there are an equal number of solute molecules and solvent molecules. The molecules of the solute are said to be "dissolved" in the solvent."
