If there are no carbonates present in the lab during this experiment, how do you perform this extraction process in absence of carbonates, reconstruct the flow chart and show the extraction of caffeine (do not replace carbonates with any other salts).

Answer:
due to lack of carbohydrates they us potato
Answer:
If there is no carbonates present in the lab during the experiment of extracting Caffeine, we can use Dicholoromethane.
Explanation:
- What is Caffeine?
Caffeine is a minor component found in traces in tea, coffee and many other organic substances.
With the help of Dicholoromethane we can perform the extraction of Caffeine instead of using carbonate salts.
- AIM: To extract Caffeine by the use of Dicholoromethane
- REQUIREMENTS: Water, sodium sulphate, tea bags, dicholoromethane, calcium chloride, sodium chloride, beaker and a Bunsen burner.
Procedure :
- Add sodium sulphate in a beaker with water and start boiling the mixture.
- Put the tea bags in the boiling mixture and let it brew for 10 - 15 minutes.
- Transfer the solution in a centrifuge.
- Add some amount of dicholoromethane to the mixture. (In case of emulsion , add sodium chloride to break it.)
- The caffeine gets extracted into dicholoromethane because it more soluble in dicholoromethane than in water.
- Then by using calcium chloride which works as a drying agent separate the organic layer of caffeine.
- Evaporate the dicholoromethane layer and isolate the caffeine layer.
Observation : After the addition of dichloromethane to the solution, two different layers were formed. The brown layer formed was the caffeine layer and the one which was transparent was dichloromethane.
Conclusion : The layers formed were due to the difference of densities. Dichloromethane being heavier settles down while Caffeine being lighter forms the upper layer.
