substances taking part in the oxidation-reduction reaction. Redox processes are ubiquitous in the environment and are crucial in all living systems. There are four types of redox reactions: a. combination reactions 2 Fe + 3 Br2 → 2 FeBr3 b. decomposition reactions 2 HgO → 2 Hg + O2 c. displacement reactions Zn + CuSO4 → Cu + ZnSO4 and d. disproportionation reactions Hg2+2 → Hg + Hg+2 Experimental: Part 2: 1. Using the information you obtained in Part 1 , plan an investigation that will allow you to determine the concentration of a FeCl2 solution of unknown concentration that your TA provides. (Hint: If you need to review an example titration, you may
