- When non-metals are dissolved in water they produce acidic oxides.
- And most metals, give rise to basic oxides.
- The formation of H+ (aq) ions in solution causes a substance's acidic nature.
- The formation of OH– (aq) ions in solution are responsible for a substance's basic nature.
- Non-metals do not react with water but the non-metal oxides do react with water and they produce acids.
- Non-metallic oxide dissolves in water to form an acid.
- CO2 + H2O → H2CO3
- Carbonic acid (H2CO3) is an acid formed by the reaction of water (H2O) with carbon oxide (CO2).
