BACKGROUND KNOWLEDGE

Learners should be familiar with many of the and work on chromatography. To help learners
ideas in this unit and are going to need their with the investigation skills, two support
knowledge of particle theory to help them templates are provided. These templates have
understand the ideas behind solutions and outlines and guidance about both planning an
solubility. investigation and dealing with the results.
The learners will also have opportunities to build Learners are unlikely to have met
on their practical skills, such as selecting suitable chromatography in any detail, but study of
equipment and making risk assessments in the solubility in topics 2.3 and 2.4 will provide
various practical opportunities in the unit. There enough background for learners to understand
