Day 1 Reflection

  • What did you do today?
    • Today we attracted caffeine from black tea. So me and my partner, Royce worked together to extract tea from the black tea. It was not a easy task but nevertheless it was fun. First we put the tea powder into the tea bags We made 8 of them. Next we boiled the water and put them in so that the caffeine can dissolve in the water. Next we poured the water which was dissolved with caffeine into the Büchner and we applied suction on it so that it can filter the coffee only. Next we added Dichloromethane into the separating funnel and we shared it and opened the lid to let some air. We repeated these steps a few times. After that we poured the lower layer into a beaker and magnesium sulphate to absorb any water residue. Then we filtered the residue. We collected the filtrate evaporated it with a rotary evaporated, which left us with solid caffeine which we had to scrape it off the flask. Next we measured the purity of the caffeine and i was satisfied with the results.

  • What did you learn today?
    • Today I learned about how to extract caffeine from drinks. Furthermore I learned the harmful effects of caffeine if we take too much. I also learnt about how the equipments work. 

  • How do you feel about today’s activities?
    • I affected me by letting me know how much caffeine is added into each drinks and how much should be added. I feel glad about the results that i made to find out the purity of caffeine 
    • My insights will be how the equipments work and how much caffeine are there in drinks. Both of them i got to find out.
