Chapter 18, Problem 18.4P

Interpretation Introduction

Interpretation:

The failure of brass plumbing fitting should be explained.

Concept Introduction:

• Electrochemical corrosion takes place when metal atoms become ions by losing electrons.
• Electrochemical corrosion takes place in an aqueous solution where ions are present in water.
• The process in which the electrochemical corrosion creates an electric circuit is known as an electrochemical cell.
• An electrochemical cell is able to generate energy from a chemical reaction or uses energy to produce a chemical reaction.
• Dezincification is a time-dependent failure caused due to dealloying of the brass over a period of time.
