Identify the correctly matched sets:
CO - neutral oxide GeO - acidic oxide PbO - basic oxide
1. CO (Carbon monoxide):
CO is a neutral oxide. It does not react with either acids or bases under normal conditions.
2. GeO (Germanium monoxide):
GeO is an acidic oxide. It reacts with bases to form salts and water.
3. PbO (Lead(II) oxide):
PbO is amphoteric, meaning it can react with both acids and bases. However, it is predominantly basic in nature.
Therefore, the correctly matched sets are:
i. CO - neutral oxide
ii. GeO - acidic oxide
PbO is amphoteric rather than strictly basic.
Thus, the correct option is (3) i, ii only.
Final Answer:
i, ii only.
