Chapter 17, Problem 17.12P

Interpretation Introduction

Interpretation:

The cathode potential required to reduce cadmium ion to cadmium has to be calculated.

Concept Introduction:

When the electric current is too small, the voltage of cell is given as

$\text{E = E(cathode)}\text{-}\text{E(anode)}$

E(cathode) is electrode’s potential which is attached to negative terminal of current source.

E(anode) is electrode’s potential which is attached to positive  terminal of current source.
