Determine the effect of the following errors on the measured absorbance for a pink colored 0.50 M solution of Cobalt (II) chloride, CoCl2(aq).
a. You rinsed the cuvette with water before adding the sample of CoCl2 (aq).
b. You used a cuvette that had previously contained 0.80 M CoCl2 (aq).
c. The solution was incorrectly made and the concentration was 0.05 M.
d. The spectrophotometer was calibrated with 0.05 M CoCl2 (aq) solution instead of water.
e. You used a cuvette that was scratched on the sides.
