3.Label the vial “Red #3 w/ Methanol”.4.Place the cap onto the vial to seal the vial and shake lightly.5.Observe the solution for solubility.a.Set aside the mixture if the solutes and solvent aren’t soluble.i.During P2 S1 we learned that the “Green Food Dye” was soluble in theMethanol.6.Repeat steps 1-5 for the Red #40 (Allura Red), Yellow #5 (Tartazine), Yellow #6 (Sunset Yellow),Green #3 (Fast Green), Blue #1 Brilliant Blue), and Blue #2 (Indigotine). 7.Transfer the soluble solutions into a cuvette.8.Set up the Spectrometer and boot up LoggerPro.a.Make sure to calibrate the Spectrometer by measuring out Methanol into a cuvette.i.Wipe the sides of the cuvette w/ Kimtech wipes.9.Place the first soluble stock solution into the Spectrometer.a.Wipe the sides of the cuvette w/ Kimtech wipes.10.Record data.a.Based on the absorption spectra (A(Absorptivity) vs. λmax(Maximum wavelength) plots)11. Repeat steps 9-10 for the other soluble stock solutions and the P2 S1 “Large green gumball w/methanol solution”12.Dispose of the solutions into the liquid waste bucket.Back-up PlanIf all the stock dyes are soluble with the Methanol solvent.
