Chromatography & Separation
Choosing the right technique, and reading a chromatogram.
What this lesson covers
Chromatography & Separation is a 10-part Class 8 Science lesson. Each part makes one point and then hands over to the next, so it can be read in a sitting or picked up again at the part you stopped on. It defines the idea in plain words before using it, works through an example step by step, breaks the topic into its parts and compares them, shows where it is used outside the textbook, names the mistakes that cost marks in an exam, ends with a recap of what to remember.
How it begins
Mixtures are not chemically bonded, so they can be separated by physical means. Choosing the right technique depends entirely on how the components differ: in size, solubility, boiling point or magnetism.
