Abstract

This article provides a comprehensive review of the corrosion behavior of lead in hydrochloric acid (HCl) solutions, a critical area of study due to its industrial relevance and environmental implications. Lead, known for its malleability and resistance to corrosion, exhibits complex degradation mechanisms when exposed to acidic environments. The research examines the electrochemical processes involved, including the dissolution of lead and the formation of soluble lead species, particularly focusing on the transition from lead carbonate to lead chloride. Various factors influencing corrosion rates, such as HCl concentration, temperature, and environmental conditions, are discussed. Additionally, this review highlights recent advancements in corrosion inhibition strategies aimed at mitigating lead degradation. Understanding these mechanisms is essential for extending the lifespan of lead-based materials in industrial applications and addressing environmental concerns associated with lead exposure.
