Chapter 17, Problem 120AE

Interpretation Introduction

Interpretation:

The discovery of USS Monitor during the Civil war and the use of sacrificial anode to prevent the corrosion of metal hull of the Monitor is given. The process by which attachment of Zinc to the hull would protect the Monitor from further corrosion is to be stated.

Concept introduction:

The corrosion is a process that involves the deterioration of metal surface in the process of moisture and oxygen. Applying the coating of more reactive metal over the less reactive metal prevents the metal to undergo corrosion.

To determine: The process by which attachment of Zinc to the hull would protect the Monitor from further corrosion.
