Question

Germanium dioxide (GeO₂) is characterized by which of the following properties?
Options
A It is a purely acidic oxide.
B It is a purely basic oxide.
C It is amphoteric, dissolving in both acids and alkalis.
Correct Answer
D It is inert and does not react with acids or alkalis.
Correct Answer

Option C is the correct answer.

Detailed Explanation

Page 22 explicitly states: 'GeO₂ • amphoteric' and provides reactions showing it dissolves in acid (GeO₂(s) + 4HCl(aq) → GeCl₄(aq) + 2H₂O(l)) and alkali (GeO₂(s) + 2OH⁻(aq) + 2H₂O(l) → [Ge(OH)₆]²⁻).

Hint

Amphoteric substances can react with both acids and bases.
