Notes

Abstract:
The synthesis of the Iron Complex was done in-situ with 3.1 equivalents of 1,10=Phenanthroline and 1 equivalent of Iron (II) Ammonium Sulfate. This gave a stock solution of 1 x 10-3M. Afterwards a titration of commercial bleach (Clorox) was performed, taking reference from General Chemistry Book, 10th EditionbyRaymond Chang, pages 156-159. Using the reference to find the concentration of NaOCl (1.33 M), which will be the substitute for HOCl that was used in the original lab report. Followed by creating three different Sodium Borate Buffers of pHs 8.78, 8.38, and 5, along with varying concentrations of NaOCl, and temperature. Monitoring this reaction using the UV-Visible Spectrophotometer at 510 nm, the rate of reaction will be observed based off the concentration as well as pH. For pHs 8.78 and 8.38, the concentrations used were 4.33 x 10-3M, 1.33 x 10-2M and 2.66 x 10-2M, while for pH 5 the concentrations were given even smaller concentrations due to how fast the reaction occurred. When comparing my results to the literature values, it was found that the reactions with bleach occurred much faster in comparison. It is later concluded that the bleach likely Cl2gas, which is a strong oxidizing agent, which would explain the differences in results.
