Fractional Distillation S2 Chemistry Materials from the Earth
Separating techniques • There are many separating techniques in chemistry. • Examples: filtration, evaporation, chromatography… • Distillation can be used to separate two liquids.
Fraction: “a group of compounds with boiling points within a given range”. Increasing viscosity Increasing boiling point Decreasing flammability Decreasing volatility View animation
