Aluminium containers are frequently used to transport trioxonitrate(V) acid because aluminium

Correct answer: Does not react with the acid

Explanation: Nitric acid (trioxonitrate(V) acid) is a strong oxidizing acid that causes passivation of aluminium. A thin, adherent layer of Al₂O₃ quickly forms on the metal surface, protecting it from further attack. Hence, aluminium containers can safely hold and transport nitric acid because the metal effectively does not react with the acid under normal conditions.

• Has a silvery-white appearance — Irrelevant to chemical storage; this is about looks, not reactivity.
• Has a low density — Makes containers lighter, but doesn’t explain resistance to nitric acid.
• Does not react with the acid — Correct. Passivating oxide film prevents attack by HNO₃.
• Does not corrode — Too general. Aluminium can corrode in other media; the key point here is its specific resistance to nitric acid due to passivation.
