- Mixture's
- Physical process
- Distilation
- Like crystallization but collects evaporated solvent by condensing it back to liquid in condenser
- Fractional distaliation
- Like distillation but separated solvent into BP's with fractionating column
- Chromatography
- Exploits mixture's solubility to separate components
- Mobile phase = solvent
- Stationary phase = paper
- more soluble - faster/ further moves down paper
- Exploits mixture's solubility to separate components
- Crystallization
- Sepertates soluble component from solvent
- Solution heated in evaporating basin to evaporate solvent
- Heating stopped when crystallization occurs. Left at room temp. until all solvent evaporated
- Solvent lost to surroundings
- Solution heated in evaporating basin to evaporate solvent
- Sepertates soluble component from solvent
- Filtration
- Separates insoluble subs. from soluble
- Isolates insoluble product + removes impurities
- Filtered solid wasted + dried to give pure, dry sub.
- Distilation
- No fixed composition
- Weak intermolecular forces
- Can be separated by physical process
- Weak intermolecular forces
- Physical process
