CHEMICAL CHANGES INVOLVING MIXING




Neutralisation

Neutralisation is a process whereby a base reacts with an acid to form salt and water only.This means that the acid has lost its acidic properties.

Like an example, when sulfuric acid is mixed with magnesium oxide the end product are magnesium sulphate and water.

Another example is when hydrochloric acid is mixed with sodium hydroxide, the mixture will become sodium chloride and water.

This is an exothermic reaction as heat is produced.
