Question: A standard electrochemical cell is made by dipping a silver electrode into a 1.0 M Ag solution and a cadmium electrode into a 1.0 M

A standard electrochemical cell is made by dipping a silver electrode into a 1.0 M Ag solution and a cadmium electrode into a 1.0 M Cd2+ solution.
a. What is the spontaneous chemical reaction, and what is the maximum potential produced by this cell?
b. What would be the effect on the potential of this cell if sodium sulfide were added to the Cd2+ half-cell and CdS were precipitated? Why?
c. What would be the effect on the potential of the cell if the size of the silver electrode were doubled?
