Question
Determine the cell potential of the following cell:
Pt|H2 (1.5 atm)|H* (0.70 M) || CI¯(0.70 M), AgCl(s)|Ag
The cathode is essentially a silver electrode, Ag+ (ag)|Ag. However, the cathode solution is saturated with silver chloride, so that the silver-ion concentration is determined by the
solubility product of AgCl (K,
-").
