The purpose of this experiment was to perform a liquid-liquid extraction method to extract the caffeine from the tea bags that were provided, and then recrystallize the caffeine. The solvents used in the experiment were an aqueous sodium carbonate and dichloromethane (DCM). Anhydrous calcium chloride pellets were used to dry the solution and emulsion layer…

The objective of the experiment was to produce two azo dyes: p-nitrobenzene azoresorcinol and methyl orange. The initial step involved mixing p-nitroaniline and resorcinol to create p-nitrobenzene azoresorcinol. In order to form the diazonium salt, we combined a solution containing p-nitroaniline dissolved in hydrochloric acid and water with a sodium nitrite solution. Subsequently, the resulting…
