Which outcome arises from prolonged exposure of galvanized steel to strongly acidic soil conditions?

💡 Explanation

When galvanized steel contacts acidic soil, hydrogen ions react with the zinc coating promoting dissolution and the formation of zinc ions. This accelerates the corrosion of the underlying steel because zinc is more electronegative, and galvanic corrosion degrades the structure faster. Therefore galvanic action occurs, rather than passivation or hydroxide formation which require less acidic environment.
