For the reactions in parts A and B, calculate the value of the equilibrium constant (Keq). In addition, calculate the electrode potential of the system at the equivalence point (Eea) of a hypothetical titration. Finally, choose the indicator from the list below that can be used to signal the end point of the hypothetical titration Number Number ECO 3 +/Co2 + 1.900 V ec Choose the correct indicator. Shown in parenthesis is the reduction potential and the number of electrons transferred in the oxidation or reduction of the indicator.
