Identify the set of acidic oxides.
- A \(\mathrm{Na}_2 \mathrm{O}, \mathrm{CaO}, \mathrm{BaO}\)
- B \(\mathrm{ZnO}, \mathrm{PbO}, \mathrm{BeO}\)
- C \(\mathrm{CO}, \mathrm{NO}, \mathrm{N}_2 \mathrm{O}\)
- D \(\mathrm{Mn}_2 \mathrm{O}_7, \mathrm{CrO}_3, \mathrm{~V}_2 \mathrm{O}_5\)
Answer & Solution
Correct Answer
(D) \(\mathrm{Mn}_2 \mathrm{O}_7, \mathrm{CrO}_3, \mathrm{~V}_2 \mathrm{O}_5\)
Step-by-step Solution
Detailed explanation
Acidic oxides \(\rightarrow \mathrm{Mn}_2 \mathrm{O}_7, \mathrm{CrO}_3, \mathrm{~V}_2 \mathrm{O}_5\) (due to higher oxidation state of central metal) Basic oxide \(\rightarrow \mathrm{Na}_2 \mathrm{O}, \mathrm{CaO}, \mathrm{BaO}\) (due to lower oxidation state of central metal)…
