We all make mistakes, and sometimes we mix substances we aren't supposed to. Fortunately, we can separate most mixtures.
Below are some commonly used separating techniques:
Filtration: this technique is used to separate a solid from a liquid. This is done by passing the mixture through a
sieve such as filter paper that will only let the liquid molecules pass through and thus 'catch' the
solids known as residue. For example, muddy water can be filtered so as to 'catch' the sand and
grit.
Distillation: this process is used to separate two liquids or solids with distinct boiling and melting points that
are far apart. The solution is heated and then vapor from the liquid with the lower boiling point flows through a tube known as the Leibig Condenser*, and is collected in a beaker. The remaining substances (with higher boiling points) remain in their original container. Thus, you have
two separated liquids.
