Q. 11.26 Classify the given oxide as neutral, acidic, basic or amphoteric. Write suitable chemical equations to show their nature.
Al2O3 = Amphoteric
Amphoteric substances react with both acids and bases. Al2O3 reacts with both NaOH and H2SO4.
Al2O3 + 2NaOH → NaAIO2
Al2O3 + 3H2SO4 → Al2(SO4)3 + 3H2O
