Suspensions

A suspension is a mixture made when a substance is insoluble, so the substance floats or sinks. There are three possible ways to separate suspensions:

  1. decanting
  2. filtering
  3. centrifuging

In today's lesson, we had to decide which method is the best. Is there actually a "best" method. We used research, an experiment (p29) and a case study (p30) to help with this.
