Caffeine Lab Report
Typical soft drinks usually contain carbonated water, caffeine, sodium benzoate, flavoring agents, and sweeteners as well for the purpose for enhancing flavor, and in the case of benzoate, to function as a preservative. Caffeine is one of the major components that is found in several beverages like coffee, energy drinks, tea, and soft drinks; just to name a few. Caffeine is known to be a powerful drug, which many people become dependent on; when they wake up in the morning it is typical to have a cup of coffee to help wake them up. While having one cup a day is not harmful to your body, some people consume four times this amount throughout their day, this is due to the fact that caffeine is a chemical that is used in order to improve mental

The glassware that was used in the experiment was (2) 100mL volumetric flask, and a (1) 250 mL beaker. At the start of the experiment, we prepared standards of benzoic acid solutions that contained 2,4,6,8, and 10 mg/L in 0.10M HCl, our group prepared the 6 and 6 mg/L standards for all the groups within the laboratory. In one of the 100mL volumetric flask it contained 6 mg/L benzoic acid + 10 mL HCl, then diluted to the mark on the flask with DI Water. In the other 100mL volumetric flask it contained 8 mg/L benzoic acid + 10 mL HCl, then diluted to the mark on the flask with DI water. Standards of caffeine were also prepared that contained 4,8,12,16 and 20 mg/L in 0.10M HCl. All other standards were prepared by other lab groups. These standards were used to obtained a series of calibration curves. We then prepared the monster energy drink, by warming 20 mL of the monster energy drink on a hot plate in order to expel CO2 and filtered the warm liquid through filter paper in order to remove any particles, after making sure the monster energy drink was cooled to room temperature; 4.00 mL were pipetted into a 100-mL volumetric flask. 10.0 mL of 0.10M HCl were added to the 100-mL volumetric flask, and diluted to the marking on the flask with DI water. A second sample was prepared by obtaining 2.00 mL of monster
