Question
What are acidic and basic oxides?
✓

Answer

  • Oxides, which dissolved in water to form acids are acidic oxides.
  • For example,
  • $\mathrm{CO}_2(\mathrm{~g})+\mathrm{H}_2 \mathrm{O}(\mathrm{l}) \rightarrow \mathrm{H}_2 \mathrm{CO}_3(\mathrm{aq})$
  • Oxides of non-metallic elements are acidic.
  • Oxides, which dissolved in water to form bases are basic oxides.
  • For example,
  • $\mathrm{Na}_2 \mathrm{O}(\mathrm{~s})+\mathrm{H}_2 \mathrm{O}(\mathrm{l}) \rightarrow 2 \mathrm{NaOH}(\mathrm{aq})$
  • Oxides of metallic elements are basic.
