1. Outline a separation scheme for isolating pure caffeine from tea. Use a flowchart that begins with the tea bag and ends with the pure caffeine. Explain what is being separated at each step throughout the procedure. 2. Why was the sodium carbonate added to the tea solution? 3. The crude caffeine isolated from tea often has a green tinge. Why? 4. What are some possible explanations for why the melting point of your isolated caffeine was lower than the...

1. Outline a separation scheme for isolating caffeine from tea. Use a flowchart similar in format to that shown in Technique 2, Section 2.2. 2. Why was the sodium carbonate added in Experiment 13A? 3. The crude caffeine isolated from tea often has a green tinge. Why? 4. What are some possible explanations for why the melting point of your isolated caffeine was lower than the literature value (236°C)? 5. An alternative procedure for removing the tannins and gallic...
4. Propose an experimental method to separate benzoic acid from biphenyl an unwanted by- product of the reaction). Keep in mind that benzoic acid and biphenyl are not soluble in water. COOH Biphenyl Benzoic acid (Hint: Think about the reactivity of the above two compounds towards bases and acids)
