Question:

A common reference electrode consists of a silver wire coated with AgCl(s) and immersed in 1 M KCl. 

AgCl(s) + e- Ag(s) + CI (1M) E = 0.2223 V

(a) What is E°cell when this electrode is a cathode in combination with a standard zinc electrode as an anode?

(b) Cite several reasons why this electrode should be easier to use than a standard hydrogen electrode.

(c) By comparing the potential of this silver–silver chloride electrode with that of the silver–silver ion electrode, determine Ksp for AgCl.
