Mixing water and sugar produces a mixture that is called a solution. In chemistry labs, this is often an experiment used to demonstrate the solubility of a solute in a solvent. In this experiment, the solute is sugar, and water is the solvent.
To form the solution, sugar dissolves in a glass of water. For dissolution to occur, there has to be more solvent than solute. Solubility is defined as how much of the solute will dissolve in the solvent.
The sugar-water solution is a homogeneous mixture because the sugar is completely distributed in the water. This homogeneous mixture is uniform in both appearance and composition. The mixture is also called a solution because the solute an solvent are in a single phase.
