SEPARATING MIXTURES
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. The diagram below illustrates this
process.
