← ScienceWhich outcome results when dissolved NaCl increases corrosion?
A)Oxygen reduction accelerates significantly✓
B)Hydrogen embrittlement risk is mitigated
C)Passive layer formation improves greatly
D)Galvanic protection effectiveness doubles
💡 Explanation
Increased NaCl promotes faster electrochemical reactions through ionic conductivity. Because oxygen reduction is crucial for iron oxidation, it accelerates corrosion; therefore the rate accelerates because of faster electron transfer, rather than cathodic prevention.
