Question

Which of the following oxides are acidic, basic, and amphoteric, respectively?

• A. MgO, Cl₂O, Al₂O₃
• B. N₂O₃, Li₂O, Al₂O₃
• C. SO₃, Al₂O₃, Na₂O
• D. P₄O₁₀, Cl₂O, CaO

Answer 1

The correct option is B

N₂O₃, Li₂O, Al₂O₃

Acidic, basic, and amphoteric oxides

Acidic oxide is an oxide that emits an acid when this works with a solution. An oxide that releases a base in groundwater as a basic oxide. An amphoteric solution is a molecule that can react chemically as either an acid or a base. Metallic oxides are basic in nature, whilst non-metallic oxides are acidic.

The correct option is B

Correct option explanation

$$\begin{gathered} {\mathrm{N}}_2{\mathrm{O}}_3\mathrm{is}\mathrm{known}\mathrm{as}\mathrm{Acidic} \\ {\mathrm{Li}}_2\mathrm{O}\mathrm{is}\mathrm{known}\mathrm{as}\mathrm{Basic} \\ {\mathrm{Al}}_2{\mathrm{O}}_3\mathrm{is}\mathrm{known}\mathrm{as}\mathrm{Amphoteric} \end{gathered}$$

The incorrect option is A

$$\begin{gathered} \mathrm{MgO}\mathrm{is}\mathrm{known}\mathrm{as}\mathrm{Basic} \\ {\mathrm{Cl}}_2\mathrm{O}\mathrm{is}\mathrm{known}\mathrm{as}\mathrm{Acidic} \\ {\mathrm{Al}}_2{\mathrm{O}}_3\mathrm{is}\mathrm{known}\mathrm{as}\mathrm{Amphoteric} \end{gathered}$$

The incorrect option is C

$$\begin{gathered} {\mathrm{SO}}_3\mathrm{is}\mathrm{known}\mathrm{as}\mathrm{Acidic} \\ {\mathrm{Al}}_2{\mathrm{O}}_3\mathrm{is}\mathrm{known}\mathrm{as}\mathrm{Amphoteric} \\ {\mathrm{Na}}_2\mathrm{O}\mathrm{is}\mathrm{known}\mathrm{as}\mathrm{Basic} \end{gathered}$$

The incorrect option is D

$$\begin{gathered} {\mathrm{P}}_4{\mathrm{O}}_{10}\mathrm{is}\mathrm{known}\mathrm{as}\mathrm{Acidic} \\ {\mathrm{Cl}}_2\mathrm{O}\mathrm{is}\mathrm{known}\mathrm{as}\mathrm{Acidic} \\ \mathrm{CaO}\mathrm{is}\mathrm{known}\mathrm{as}\mathrm{Basic} \end{gathered}$$

Conclusion

Hence the correct option is B.
