- Separation Techniques
- Miscible Liquids Mix Together but Immiscible Liquids Don't.
- Some liquids mix together, others don't.
- Liquids the mix are miscible, e.g. milk and tea.
- Liquids that don't mix properly are immiscible, e.g. oil and water.
- Use a Separating Funnel to Separate Immiscible Liquids.
- Shake the two liquids together.
- Let them stand, allowing them to separate in to layers.
- Use a separating funnel with a tap to separate the layers.
- The tap can be opened to drain of the lower layer in to a beaker.
- Fractional Distillation Separates Out Miscible Liquids
- Mixture is headed, allowing the liquids to become gasses which rise up the column and cool down.
- When the gases are cooled enough, they will condense.
- Some mixtures condense at different temperatures, allowing them to be collected separately.
