Principles of Industrial Electrochemistry

Consider a cell consisting of a silver wire coated with solid silver chloride and a zinc wire in an aqueous solution of zinc chloride at 25oC.

a)   Calculate the reversible potential difference between the two wires when the activity of dissolved zinc chloride is 0.01 molal (mol/kg H20). Indicate the direction of the spontaneous reaction and the sign of the electrodes.

b)   Calculate the reversible potential difference between the two wires when the electrolyte is saturated with an excess of solid zinc chloride. Determine the activity of dissolved zinc chloride in a saturated solution.

Standard chemical potentials at 25oC:

AgCl (crystal)                            mo = -109.8 kJ/mol

ZnCl2 (crystal)                            mo = -369.4 kJ/mol

ZnCl2 (dissolved in H20)            mo = -409.5 kJ/mol
