← ScienceWhich consequence result when sacrificial anodes corrode in seawater?
A)Galvanic protection prevents steel corrosion✓
B)Steel structures exhibit cathodic corrosion
C)Increased chloride ion penetration occurs
D)Passivation layers spontaneously form on steel
💡 Explanation
Because a less noble metal oxidizes preferentially due to galvanic interaction giving cathodic protection, therefore the steel remains intact rather than undergoing oxidation; this is cathodic protection, rather than corrosion, via increased ion penetration.
