Spectrophotometric Assay of Paracetamol
You are required to write a lab report based on results obtained from this experiment. The lab report will describe and discuss the spectrophotometric assay of paracetamol. The collected data must be presented, analysed, andinterpreted. The lab report is followed by a few calculation questions which you need to answer and provide an explanation for your solution. .Practical details: The maximum absorbance wavelength (λmax) of paracetamol is 243 nm.
In order to assess the content of paracetamol in an unknown sample, we need first to prepare a calibration curve which displays the relationship between absorbance and concentrationYou will have the following:Paracetamol stock solution (10 mg/litre) in 5% ethanol/water.
Dilution solution 5% ethanol/waterSamples containing paracetamolGlassware, volumetric flasks, tubes to prepare your solutions, micropipettes, and UV cuvettes. Preparation of standard solutionsPrepare standard solutions of paracetamol starting from the stock solutions with the following concentrations. The final volume of each solution should be 5 ml.Calculate the needed volumes of both the stock solution and the dilution solution to prepare your standards 1-5.
