← ScienceWhich risk increases when applying excessive voltage during aluminum oxide electrolytic cell production?
A)Disruptions in ionic lattice energies✓
B)Covalent bond formation increases
C)Metallic bonding strengthens overall
D)Hydrogen bond network stabilizes oxide
💡 Explanation
Applying excessive voltage can disrupt orderly deposition by galvanic anodization because increased energy input overwhelms the inherent stabilization from strong electrostatic forces. This causes disruptions in ionic lattice energies, therefore fewer defect-free regions, rather than stronger covalent bonds or hydrogen bonds which depend on electronegativity differences.
