In chemistry, a solute is a substance that is dissolved in a solution, which is usually a liquid. A solution is a homogeneous mixture of one or more solutes dissolved in a solvent. The solvent is the substance that is present in the greatest amount, while the solute is the substance that is being dissolved/15%3A_Water/15.04%3A_Solute_and_Solvent). 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. The particles of solute in a solution cannot be seen by the naked eye. Solute particles can be atoms, ions, or molecules, depending on the type of solute/15%3A_Water/15.04%3A_Solute_and_Solvent). Examples of solutes include salt, sugar, and copper sulfate.
