Explain how the zinc anode dissolves

WebWhen an anode is missing or largely wasted away, the metal component it was installed to protect begins to dissolve — guaranteed. How much zinc. The amount of protection a zinc anode provides depends on its surface … WebFor steel, the typical anodic oxidation reaction is: Fe = Fe 2+ + 2e ¯ This reaction is accompanied by the following: Fe 2+ + 2OH ¯ = Fe (OH) 2 The ferrous hydroxide then combines with oxygen and water to produce ferric hydroxide, Fe (OH) 3, which becomes common iron rust when dehydrated to Fe 2 O 3.
