Investigation of Iron Nail Corrosion under Different Water Conditions

Abstract

Corrosion is a common electrochemical process that affects many metal structures in everyday life. This study investigated how different water conditions affected the corrosion rate of iron nails after 9 days of exposure. Iron nails were submerged in deionized water, tap water, salt water (3% NaCl), and an acidic HCl solution under controlled conditions. Corrosion rates were determined by measuring mass loss after oxidized material was removed using a rust remover. Results showed that the acidic HCl solution produced the highest corrosion rate, while deionized water produced the lowest corrosion rate, and salt water showed a slightly lower corrosion rate than tap water. These findings suggest that both pH and dissolved ion concentration influence the corrosion behavior of iron under different water conditions.
