|
Reflux |
- continuously boil while reaction happens - heat without evaporating reactant and products - anti bumping granules - water enters condenser at bottom - water leaves condenser at top - vapour condenses in condenser and drips back into flask |
|
|
Distillation |
- product in flask needs to be purified - method used to separate pure liquid from impurities - vapour reaches cold condenser and becomes liquid - liquid drips into conical flask |
|
|
Purifying Organic Products |
- water is mixed in with organic product - organic layer floats on aqueous layer - separate layers using separating funnel - remove stopper so that aqueous layer leaves |
|
|
Acid Impurities |
- add sodium carbonate - reacts to from CO2 - release CO2 |
|
|
Drying Organic Product |
- add drying agent - anhydrous salt MgSO4 - takes up water to become hydrated - filter |
|
|
Refistillation |
- some organic products have boiling points close together - some organic products have boiling points close together- 2nd distillation used to separate them- only collect product with boiling point you need - some organic products have boiling points close together- 2nd distillation used to separate them- only collect product with boiling point you need - 2nd distillation used to separate them - only collect product with boiling point you need |
