3. Introduction
• When sugar is added to water, the sugar
dissolve and the sugar goes to the solution.
However, infinite amount of sugar cannot be
dissolved into a fixed volume of water. When
as much sugar has been dissolved into a
solution as possible, the solution is said to be
saturated.
4. • The saturation point is different at different
temperatures. The higher temperature, the
more sugar can be held in solution.
• When cooking up a batch of candy, sugar and
various other ingredients one needs an
extremely high temperature. At these high
temperatures, the sugar remains in solution,
even though much of the water has boiled
away. But when the candy is through cooking
and begins to cool, there is more sugar than is
normally possible. The solution is said to be
supersaturated with sugar.
