Objective-Centrifuge concentration gradient solutions to observe absorbance in each -Observe pH changes in crystal violet hydrogels with the addition of HCl or NaOH ProceduresPart 1: Preparing Concentration Gradients for UV-Vis Measurements 1) Centrifuge 6 solutions containing varying amounts of R6G prepared on 03/27/2013 for 5 minutes at 11200rpm 3 times. 2) Make the following stock solutions to compare the supernatant absorbances to:
3) Take UV-Vis spectra of stock solutions and supernatants Data
