This module is concerned with interpreting solubility curves for either ionic solids or gases dissolved in water. Solubility curves are graphs where the solubility of the substance in g per 100 g water is plotted against temperature.
On completion of the module you should be able to
- describe, using appropriate terminology
the nature of a saturated solution
the variation in solubility of both an ionic solid and a gas with temperature
the variation in solubility of a gas with the pressure of the gas over the solution
the difference between isolation of an ionic solid by crystallisation and evaporation
- deduce, from the solubility curve,
the solubility in g per 100 g of water of an ionic solid or gas at a particular temperature
the maximum mass of solute that will dissolve in a given volume of water at a particular temperature
whether a given masses of solute and solvent mix to give a saturated solution
the temperature at which crystallisation on cooling a saturated solution
