Why does alkaline medium inhibit rusting of iron?
Answers
Answer:
Rusting of iron is due to the presence of H+ ions. Alkaline medium reduces the concentration of H+ ions by increasing the concentration of OH- ions. (It will neutralize H+ ions) and inhibit rusting.
The Reason for alkaline medium to inhibit rusting of iron.
Explanation:
The inhibition of iron corrosion in alkaline solutions is due to the anodic formation of a film of a ferrous compound, which is usually ferrous hydroxide, but the composition may be mixed in the presence of anions which yield less soluble ferrous salts, such as carbonate. Subsequently, the ferrous compounds are oxidized to anhydrous cubic oxide; as a result, the film thickens until it prevents ferrous ions from passing into solution.
