You have synthesized a redox reagent that is a complex between cobalt and six ammonia molecules ([Co(NH3)6] 3+/2+). It cycles between the Co(II) and Co(III) oxidation states. Unfortunately, after you complete your synthesis, you learn that your potentiostat is broken and you have no way to measure the reduction potential of your compound. Fortunately, you realize that you have sufficient information from other experiments and from data tables to determine the potential for this reagent. This information is: The standard...
