Question

By giving examples explain basic oxides.

Answer 1

1. An oxide that exhibits the property of a base is called a basic oxide.
2. Since they are basic, they react with an acid to form a salt.
3. These oxides are formed by the reaction of Oxygen with metals like Magnesium (Mg), Sodium (Na), etc.
4. Basic oxide reacts with water to form a base as shown in the reaction below.

$$\begin{gathered} \mathrm{MgO}\left(\mathrm{s}\right)+{\mathrm{H}}_2\mathrm{O}\left(\mathrm{l}\right)\to \mathrm{Mg}{\left(\mathrm{OH}\right)}_2\left(\mathrm{aq}\right) \\ (\mathrm{Magnesium}\mathrm{oxide})\left(\mathrm{Water}\right)(\mathrm{Magnesium}\mathrm{hydroxide}) \end{gathered}$$

Example of basic oxide: Magnesium oxide (MgO), CaO, K₂O, Na₂O.
