Chapter 17, Problem 39E

Interpretation Introduction

Interpretation:

The direction of electron flow and the movements of nitrate ions in the salt bridge of the given voltaic cell is to be drawn.

Concept introduction:

In an electrochemical cell, two electrodes are connected by a wire and electrons are free to move between two compartments. Each compartment is known as a half-cell. The reduction is defined as the gain of electrons and oxidation is defined as the loss of electrons. The substance that is oxidized is a reducing agent and the substance that is reduced is an oxidizing agent.
