There are three types of solution saturation:
• An unsaturated solution is when there is less solute than the solvent. The solvent is able to dissolve the solute completely and can still dissolve any additional solute.
• A saturated solution is when the solvent has dissolved the maximum amount of solute at a specific temperature.
• A supersaturated solution is when there is a greater amount of solute dissolved in the solvent at a specific temperature than is needed to obtain saturation.
A supersaturated solution of sucrose (C12H22O11) is made by dissolving sucrose in hot water and slowly letting the solution cool to room temperature. After a long time, the excess sucrose crystallizes out of the solution. Indicate whether each of the following statements is true or false:
After the excess sucrose has crystallized out, the rate of sucrose molecules leaving the surface of the crystals to be hydrated by water is equal to the rate of sucrose molecules in water attaching to the surface of the crystals.
