← ScienceWhich outcome results at the interface when differential oxygen concentrations sustain microbiologically induced corrosion of steel submerged in seawater?
A)Increased chloride ion transport✓
B)Uniform passivation layer formation
C)Elevated cathodic protection current
D)Decreased biofilm attachment strength
💡 Explanation
Increased chloride ion transport occurs because *ionic* transport is enhanced by increased surface charge density during differential aeration; the increased concentration of hydroxyl ions generates a charge, leading to *ionic* migration; therefore increased local breakdown, rather than uniform protection occurs.
