REACTION OF HYDROGEN PEROXIDE AND BLEACH II. REACTION OF IRON (II) WITH 1,10 PHENANTHROLINE Purpose and Method Things to think about: What is the goal of this experiment? Explain how it is accomplished. What is the general method (not step by step detailed procedure) that you will be using to achieve this goal? How will you process the data that you record in lab? (What calculations will you use and how do you obtain all of the values to plug into those equations?) Part I (3 pts) Purpose- The purpose was to determine the hydrogen peroxide (H2O2)-bleach (NaOCl) stoichiometry. We were to find the reaction mole ratio and the coefficients on the reactant side. Procedure- We first got specifically measured amounts of hydrogen peroxide and bleach. The bleach went into a flask and the hydrogen peroxide was placed in a vile and
