Separating a mixture of kerosene and petrol can be effectively done using distillation. Since the two substances have different boiling points (kerosene around 150-275°C and petrol around 95-200°C), heating the mixture allows the petrol to evaporate first. Capture and condense the petrol vapors to separate it from kerosene. This method requires precise temperature control and safety measures due to the flammable nature of both liquids.

FAQs & Answers

  1. Why does distillation work to separate kerosene and petrol? Distillation separates kerosene and petrol because they have different boiling points; petrol evaporates first at a lower temperature, allowing it to be separated from kerosene.
  2. What safety precautions should be taken when distilling flammable liquids like kerosene and petrol? Ensure proper ventilation, use flameproof equipment, monitor temperature carefully, and keep sources of ignition away to safely distill flammable liquids like kerosene and petrol.
  3. Can kerosene and petrol be separated without distillation? Due to their similar liquid nature, distillation is the most effective method to separate kerosene and petrol; alternative methods are generally less practical or ineffective.
