Practice midterm 2016 #8A

Postby YsabelCheang1H » Mon Feb 13, 2017 6:20 pm

A standard electrochemical cell is made by placing a silver electrode into a 1.0M Ag+ solution and a cadmium electrode into a 1.0M Cd2+ solution. What is the redox reaction and what is the maximum potential produced by this cell?

In this question I was wondering how to tell which one is the anode(oxidized) and which is the cathode(reduced)?

You look at the cell potentials. Whichever one is larger is the cathode and is therefore being reduced. The smaller, more negative value is the cell potential for the anode and is therefore oxidized.
