Objective

-Centrifuge concentration gradient solutions to observe absorbance in each

-Observe pH changes in crystal violet hydrogels with the addition of HCl or NaOH

Procedures

Part 1: preparing concentration gradient 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) Measure the absorbance of all 3 supernatants as well as a stock solution.
