Question

Write the properties of acidic oxides.

Answer 1

Definition

An oxide that dissolves in water to give an acid is called an acidic oxide.

Example: ${\mathrm{CO}}_2$

Carbon dioxide(${\mathrm{CO}}_2$) dissolves in water and slowly reacts with water to produce carbonic acid (${\mathrm{H}}_2{\mathrm{CO}}_3$).

Chemical equation:

${\mathrm{H}}_2\mathrm{O}\left(\mathrm{aq}\right)+{\mathrm{CO}}_2\left(\mathrm{g}\right)\to {\mathrm{H}}_2{\mathrm{CO}}_3\left(\mathrm{aq}\right)$

Properties of acidic oxides

• Acidic oxides are compounds that can form an acidic solution when dissolved in water.
• They are also known as acid anhydrides
• Acidic oxides are formed when oxygen reacts with non-metals.
• They react with bases forming a salt.
• They do not react with acids.
• Their pH is increased when dissolved in water.
• They have covalent bonds.
