In order to obtain crude caffeine from the contents of a tea bag, the processes of extraction was used to remove the caffeine from 2.673 grams of tea leaves. The caffeine was extracted in a separator funnel using dichloromethane and water. The experimental procedure called for three separate extractions using 5 mL of dichloromethane each time. However, one large extraction using 15 mL of dichloromethane was performed due to a misunderstanding while reading the directions. Therefore, the amount of crude caffeine obtained from extraction was very small, and many more impurities were also extracted. The amount of crude caffeine extracted was 0.094 g. When this value is compared to total mass of the tea leaves, the percent yield was determined to be 3.52 %. According to caffeineinformer.com, tea seeped for 5 minutes should contain around 0.047 g of caffeine. When the extracted value is compared to this
The experiment extraction was used to determine the amount of crude caffeine in 2.673 grams of tea leaves. Dichloromethane and water were used with a separatory funnel in order to extract the caffeine from the tea leaves. Three extractions using 5mL of dichloromethane was directed in the experimental procedure; however, 15mL of dichloromethane was used to complete one extraction due to misinterpreting the experimental procedure. Because of this mistake, a very minimal amount of caffeine along with many impurities were extracted. A total of 0.094 grams of caffeine was extracted during this step, which gives a percent yield of 3.52% when compared to the total mass of tea leaves. As caffeineinformer.com states, there are 0.047 grams of caffeine

To decrease drowsiness,it blocks your adenosine receptors. Adenosine is the chemical that tells your body that it is tired, which is our body’s way of trying to get us to rest. When we block the receptors, your body stops saying that it is tired, and you feel like you have an energy boost. Another thing that caffeine does is produce dopamine. Dopamine is the chemical that makes you feel happy. The caffeine increases the levels of dopamine being created, and gives your mood a boost too. Caffeine has also been shown to temporarily create other benefits too,such as someones ability to learn, improved reflexes, being able to think clearer and better memory.
