The purpose of this experiment is to determine and compare the mass of aspirin in three different brands of tablets, each with the same reported dosage of 325mg. In pursuit of this objective, a calibration curve for sodium salicylate will be established. Its absorbance readings will then be used to perform a colorimetric analysis to determine the amount of aspirin in a given tablet. To most effectively compare the masses of aspirin between brands, errors by the spectrophotometer and dilution techniques will be minimized.

It is hypothesized that there is no statistical difference in the amount of aspirin between the three brands. Additionally, it is hypothesized that the average amount of aspirin determined in each brand of tablet varies no more than 5% from the manufacturer’s claim of 325mg.
