Sample questions
-
1.What is meant by the amphoteric nature of aluminium? It refers to aluminium's ability to:
- A.react only with acids to form salts and hydrogen gas, as shown by 2Al + 6HCl → 2AlCl₃ + 3H₂.
- B.react with both acids and bases, forming salts and hydrogen gas, illustrated by reactions with HCl and NaOH.
- C.form a protective oxide layer that prevents further reaction with acids or bases.
- D.react exclusively with bases to produce aluminate salts, such as 2Al + 2NaOH + 2H₂O → 2NaAlO₂ + 3H₂.
-

- A.Duralumin
- B.Brass
- C.Bronze
- D.Solder
-
3.Bronze is an alloy primarily composed of copper and which other metal?
- A.Zinc
- B.Tin
- C.Aluminium

-
4.Which of the following equations correctly represents the burning of aluminium in air?
- A.4Al + 3O₂ → 2Al₂O₃
- B.2Al + N₂ → 2AlN
- C.4Al + 3O₂ → 2Al₂O₃; 2Al + N₂ → 2AlN
