In
chemistry, a
solution is a
homogeneous mixture composed of two or more substances. In such a mixture, a
solute is a substance
dissolved in another substance, known as a
solvent. The solution more or less takes on the characteristics of the solvent including its phase, and the solvent is commonly the major fraction of the mixture. The
concentration of a solute in a solution is a measure of how much of that solute is dissolved in the solvent, with regard to how much solvent is present.
