Question

If X is a non-metal, its oxide ${\mathrm{X}}_2{\mathrm{O}}_3$ is expected to be a _______oxide.

Answer 1

Non-metallic oxide:

• The non-metal mainly forms Acidic oxides.
• Hence, if X is a non-metal, its oxide ${\mathrm{X}}_2{\mathrm{O}}_3$ is expected to be an acidic oxide.
• Example: Non-metals like Sulfur and Carbon react with oxygen to form Sulfur dioxide and Carbon dioxide which are both known to be acidic oxides.
• Thus all non-metals form covalent oxides with oxygen that react with water to form acids or form salts.

Hence, If X is a non-metal, its oxide ${\mathrm{X}}_2{\mathrm{O}}_3$ is expected to be an acidic oxide.
