Objective Finished filtering 40% beads Put 40% beads in acid Put 25% beads in dye Description Beads in dye procedure: All the beads have 5mL of acid in them from previous pH tests. Last week a 1/5 carmine dye solution was prepared using 1mL of the stock dye and 5mL of water When placing this dye in the vials a dye solution with a 1/10 ratio will result. This solution will be allowed to sit until next lab. If the solution is completely clear, more dye will be added and allowed to sit If the solution is not clear anymore (i.e. the beads have been saturated) then the beads will be filtered out and we will run UV-Vis on the resulting solution. Adsorption capacity will be determined using final concentration and amount of dye added. Data Add data and results here...
