- 2Name it1. Pear-shaped flask
2. Receiver
3. Screw-tap adaptor
4. Condensor
5. Still head - 3Heating under refluxAdd anti-bumping granules to ensure smooth boiling.
Enables a liquid to be continually boiled whilst a reaction takes place
Prevents volatile components from escaping and flask from boiling dry as vapour condenses and drips back down into flask - 4DistillationUsed to separate pure liquid from impurities

- 8Purifying organic products1. Separate with a separating funnel
2. Ensure tap of separating funnel is closed
3. Pour mix of liquids into sf, place a stopper in the top of the funnel, invert to mix the contents.
4. Allow the layers to settle.
5. add water to see which layer increases in volume - this is the aq layer.
6. Place a conical flask under the sf, remove stopper and open tap until the whole of the lower layer has left the funnel.
7. Place a second conical flask under the separating funnel to collect the other layer - 9Drying the organic productUse anhydrous inorganic salt like CaCl2/MgSO4
- 10RedistillationIf organic liquids have similar bpt clean out and redistill at a bpt within the range of the desired product.
