Question

By giving examples explain acidic oxides.

Answer 1

1. An oxide that exhibits the property of acids is called acidic oxide.
2. Since they are acidic, they react with a base to form a salt.
3. Acidic oxide reacts with water to form an acid as shown in the reaction below$$\begin{gathered} {\mathrm{SO}}_3\left(\mathrm{l}\right)+{\mathrm{H}}_2\mathrm{O}\left(\mathrm{l}\right)\to {\mathrm{H}}_2{\mathrm{SO}}_4\left(\mathrm{aq}\right) \\ (\mathrm{Sulphur}\mathrm{trioxide})\left(\mathrm{Water}\right)(\mathrm{Sulphuric}\mathrm{acid}) \end{gathered}$$
4. These oxides are formed by the reaction of Oxygen with non-metals like Nitrogen (N), Sulphur (S), etc.
5. Examples of acidic oxide: Nitrogen Dioxide$\left({\mathrm{NO}}_2\right)$, Sulphur trioxide$\left({\mathrm{SO}}_3\right)$.
