Chapter 17, Problem 35E

Interpretation Introduction

Interpretation:

The set up of a galvanic cell is given. The reducing agent and the oxidizing agent, and the direction of the electron flow are to be stated.

Concept introduction:

In galvanic cell, the oxidation occurs at anode while reduction occurs at cathode. The species that undergoes oxidation reaction loses electrons and reduces other species. Therefore, it acts as a reducing agent. On the other hand, the species that undergoes reduction reaction gains electrons and oxidizes other species. Therefore, it acts as an oxidizing agent.

To determine: The oxidizing agent and the reducing agent, and the direction of the electron flow.
