← ScienceWhich outcome accelerates corrosion when stainless steel connects to cast iron in seawater?
A)Galvanic corrosion forms iron oxides✓
B)Passivation maintains corrosion inhibition
C)Sacrificial anode protects the steel
D)Uniform corrosion evenly erodes materials
💡 Explanation
Galvanic corrosion occurs because the difference in electrochemical potential promotes electron flow through the seawater (electrolyte) resulting in oxidation of the iron anode and metal loss, therefore accelerating corrosion rather than preventing it, because passivation requires specific oxidation potentials.
