The technique consists of selectively precipitating only a few kinds of metal ions at a time under given sets of conditions. Consecutive precipitation steps become progressively less selective until almost all the metal ions are precipitated. Other additional steps are needed to separate metal ions that precipitate together.

This model provides hands-on practice of separating a mixture of substances that are often encountered in chemical synthesis and chemical extraction processes. The ions in the mixture are separated by selective precipitation, selective dissolution, and characteristic reactions enforced based on common ion effects, pH effect, coordination complex formation, and redox reactions.

For example, for th...When the solubilities of compounds containing various cations combined with a given anion are compared, a solubility trend that follows the order in the periodic table is expected. For example, for the solubilities of the sulfate salts, the solubility is expected either to increase or decrease as we go down the alkaline earth family. These solubility properties will be used to identify an unknown compound containing a cation.

The mobile phase carries the sample through a packed or capillary column that separates the sample's components based on their ability to partition between the mobile phase and the stationary phase. By adjusting conditions it usually is possible to design a separation so that analytes elute by themselves, even when the mixture is complex.

In this section we consider absorption spectrometry in which we measure the absorbance of IR light as it passes through a gas, solution, liquid, or solid sample.

In a packed column, larger samples can be handled, whereas capillary columns allow separation of more complex mixtures. Elution order in gas-liquid chromatography depends on solutes' boiling points and interactions with the stationary phase.
