REQUIRED PRACTICAL PHOTOSYNTHESIS

• What are the steps to analyze a sample of water for purity?

  1. Check the pH using universal indicator paper.
  2. Weigh an empty evaporating basin.
  3. Fill the basin with the water sample and heat until evaporated.
  4. Weigh the basin again to check for dissolved solids.
• What is the process of purifying water by distillation?


  1. Heat the water in a conical flask.
  2. Water evaporates and forms vapor.
  3. Vapor travels through a delivery tube to a cold test tube.
  4. Vapor condenses back into liquid water.
  5. Resulting water is distilled and pure.
