Unformatted text preview: Spectrophotometry and the Beer-Lambert Law Abstract: This experiment explores the correlation between absorbance of aspirin solutions and their concentrations. Solutions of varying were examined using a spectrophotometer and then using the transmittance formulas and Beer’s law to determine the concentration of an unknown aspirin content in a commercial brand of aspirin. It was determined that the unknown sample was very close in concentration to the third {c} sample created. Introduction: The concentration of an over the counter aspirin was to be determined using a series of created solutions of known concentrations and then compared to find out what the concentration is. To find this the Beer’s-Lambert law was exercised. %T can be read off a spectrometer which can then be used in the following formulas %T=Tx100 Absorbance= -log(T)...
