Supersaturation

In physical chemistry, supersaturation occurs with a solution when the concentration of a solute exceeds the concentration specified by the value of solubility at equilibrium. Most commonly the term i
Crystallized sugar (rock candy) is made by adding a seed crystal to a supersaturated solution of table sugar and water. The multiple crystals on the right were grown from a sugar cube, while the left was grown from a single seed taken from the right. A red dye was added to the solution for the left crystal, but was insoluble with the solid sugar, and only traces remain while the rest precipitated out.
