- Chromatography – involves solvent separation on a solid medium and uses the different rate of movement of the solvent
- Decanting – separating a liquid from a solid/liquid by pouring out the top layer leaving the unwanted layer behind
- Distillation takes advantage of differences in boiling points allowing for liquids to be separated. For example water and food dye.
- Evaporation removes a liquid from a solution to leave a solid material. It is important to remember evaporation can occur at room temperature for water – it is different from boiling point. Increasing temperature increases rate of evaporation.
- Filtration separates solids of different sizes or allows a solid to be removed from a liquid. Think of using filter paper to remove sucrose from a water solution.
- Fractional distillation – separating solutions with similar boiling points.
- Separating funnel – used to separate immiscible liquids with different densities.
A carbonate + acid –> carbon dioxide + water + salt
