Question
Data eZn|Zn2+,red o = - 0.762 V eAg|Ag+,red o = + 0.80 V 2. Write a Cell Reaction for the above Cell. Write appropriate Half-Reactions. Identify the Oxidation and Reduction.
Draw a Cell Diagram for this Cell.
Determine eCell o if 0.001 M ZnSO4 and 0.001 M Ag2SO4 are used as electrolytes. i) First calculate eCell o . ii) Then calculate the ionic strength I (Eq. 11) for the ZnSO4 and Ag2SO4 electrolyte solutions. iii) Use the Debye-Huckel equation (Eq. 10) to determine the activity coefficients gZn2+ and gAg+. iv) Finally determine eCell using the Nernst Equation (Eqs. 7 and 9).
