Aluminium oxide demonstrates amphoteric behavior as it interacts with both acids and bases to produce salt and water. In the reaction Al2O3 + H2O + 2NaOH → NaAlO2 + H2O, it reacts with a base, while in the reaction Al2O3 + xH2O + HCl → AlCl3 + H2O, it reacts with an acid. What type of acid is HCl in this context?

1. Highly basic substance
2. Mildly acidic compound
3. Highly acidic substance
4. Weakly basic compound

Correct answer: Highly acidic substance

Solution

HCl is a highly acidic substance as it completely dissociates in water to produce H+ ions, which is characteristic of strong acids
