Chapter 4 - Reactions

We met with Pedro again this week to discuss/consult with him about the procedure. The dye of choice was narrowed to tartrazine or potassium permanganate. Although a relation between the absorbance and time could be used to characterize the release rate, knowing the solution of the dye in water will also be valuable. To make this conversion, a stock solution of potassium permanganate will be created and solutions with varying concentrations will be produced from this. Their absorbances will be measured using a UV spectrometer to create a calibration curve for Beer's Law. We also set up another time with Pedro this upcoming weekend to meet to actually perform the experiment.
