Ag + + e - ? Ag(s) E° = 0.80 V
Cu 2+ + 2e - ? Cu(s) E° = 0.34 V
In a galvanic cell, the silver compartment contains a silver electrode and excess AgCl(s) (K sp = 1.6 × 10 -10 ). The copper compartment contains a copper electrode, and [Cu 2+ ] = 2.0 M.

A. Calculate the potential for this cell at 25°C.
B. Assuming 1.0 L of 2.0 M Cu 2+ in the copper compartment, calculate how many moles of NH 3 would have to be added to establish the cell potential at 0.52 V at 25°C (assume no volume change on addition of NH 3 ).
Cu 2+ + 4NH 3 Cu(NH 3 ) 4 S1U112+ K f = 1.0 ×10 13
