Extension Question: Scientists looking for new substances in plants grind up the plants with methanol. This solvent
dissolves many plant compounds. However, methanol is flammable and toxic (especially if the
vapour is inhaled). Large crystals can be made to help scientists work out what the compounds are
made of.
How could you make pure, dry crystals of the substance using methanol?
Consider the hazards involved in your experiment and how to reduce the risks.
You could use a flow-map to show your method, and you may want to include labelled diagrams.
