1. The hypothetical elements, named A, B, C, and D are all found to produce divalent aqueous ions, A²⁺, B²⁺, C²⁺, and D²⁺. A series of chemical reactions were designed to determine the reactivity of these elements relative to each other. Use the results of the reactions to construct a reduction potential series, similar to appendix L in the textbook, but ordered by reduction potential, not alphabetically. List the element that is the strongest oxidizing agent at the top of this series and the strongest reducing agent at the bottom. Provide a description of the series, explaining what is being communicated about the elements

B²⁺ + D --> B + D²⁺

B²⁺ + A -->No reaction

D²⁺ + C --> D + C²⁺
