Identify basic oxide from following.
- A \(\mathrm{SO}_3\)
- B \(\text{NO}\)
- C \(\mathrm{Al}_2 \mathrm{O}_3\)
- D \(\text{CaO}\)
Answer & Solution
Correct Answer
(D) \(\text{CaO}\)
Step-by-step Solution
Detailed explanation
\(\mathrm{SO}_3=\) Acidic oxide, \(\mathrm{NO}=\) Neutral oxide
\(\mathrm{Al}_2 \mathrm{O}_3=\) Amphoteric oxide, \(\mathrm{CaO}=\) Basic oxide
Oxides of the metals of Group I and II are basic, while that of non-metals are acidic.
