Organic techniques - purifying organic liquids

(0)
An A-Level Chemistry resource on purification of organic liquids. The handout includes labelled diagrams and information on the organic techniques of reflux, distillation, washing and drying. Includes diagrams of heating by reflux, distillation, separating (tap) funnel and drying agent. With each diagram is information about what each technique is used for. E.g. purpose of washing with HCl, NaHCO3 or water. Purpose of a drying agent with relevant examples. Why antibumping granules are required in a pear shaped flask. Why the water goes in the bottom of a condenser and out at the top and much more. The information helps students prepare for questions on A-Level required practicals on organic chemistry.
