← ScienceWhich outcome reduces conductivity when iron corrodes in seawater?
A)Formation of insoluble ionic compounds✓
B)Increase in metallic bond strength
C)Creation of free electron pathways
D)Reduction in surface area roughness
💡 Explanation
The formation of insoluble ionic compounds on the iron surface decreases conductivity because electron mobility is hindered by the non-conductive rust layer, resulting from redox and precipitation reactions. Therefore, conductivity reduction occurs rather than increased electron mobility or stronger metallic bonds.
