← ScienceWhich outcome is expedited when chloride concentration diminishes near galvanized steel?
A)Faster dissolution of the zinc layer✓
B)Increased hydroxide film formation rate
C)Suppressed iron oxide electrochemical reduction
D)Decreased diffusion of oxygen molecules
💡 Explanation
Galvanized steel relies on zinc's sacrificial corrosion through the mechanism of electrochemical oxidization; fewer chlorides hinder the stabilizing oxide layer, because the lower ionic concentration causes zinc dissolution to be favored electrochemically, therefore zinc erodes faster rather than benefiting from passivation.
