Chapter 18, Problem 18.13QP

(a)

Interpretation Introduction

Interpretation: The questions based on the porous separator between the two halves of an electrochemical cell are to be answered.

Concept introduction: An electrochemical cell is a device which converts the chemical energy to electrical energy. This chemical energy generates by processing the redox reaction. Redox reaction is the combination of two half reactions. One half reactions are known as reduction half while other is oxidation half.

Salt bridge, also known as porous bridge is a U-shaped hollow device which is filled with KOH or other electrolytes. It is used to maintain the electrical neutrality during the process of redox reactions in two different compartments

To determine: A description of the flow of electric charge between the two half–cells.

(b)

Interpretation Introduction

To determine: An explanation corresponding to the given fact that a piece of wire could not perform the same function.
