Chapter 19.2, Problem 3RC

Interpretation Introduction

Interpretation: The migration of ions in the salt bridge of the given cell is to be determined from the given option.

Concept introduction:

• The substance that easily be reduced in a reaction is represented as an oxidizing agent. For metal cations, a good oxidizing agent can be determined by the standard reduction potential values.
• Half-cell: In the electrochemical cell, both oxidation and reduction occurs. Oxidation occurs at the anode and reduction occurs at the cathode.
• Salt bridge is connected between two half-cells to balance the charge.
