1.	What product(s) is/are formed when aluminum metal is treated with concentrated nitric acid?(a) Al (NO3) 3(b) Al (NO2) 3 + H2(c) Al2O3(d) Al4O3I got this question during an online interview.The question is from P-Block Elements in division P-Block Elements of Chemistry – Class 12
Answer» Correct option is (C) Al2O3 The best explanation: Aluminum does not DISSOLVE in nitric acid. This is because treatment with nitric acid results in the formation of a tough OXIDE layer. This oxide layer prevents it from further REACTING with the oxide. HENCE, the compound formed is Al2O3 i.e. aluminum (III) oxide.
