Key Stage 4
Meaning
Acidity is the strength of an acid determined by how easily Hydrogen ions are formed when the acid dissolves in water.
About Acidity
- When a compound does dissolve in water to produce an acid not all of the Hydrogen ions will dissociate from the compound.
- The strength of an acid, or its acidity, is determined by how easily Hydrogen ions are formed.
- The more easily Hydrogen ions form, the stronger the acid (the higher the acidity).
