Ionisation means forming ions from an initially uncharged substance. Acid strength describes how completely an acid ionises in water, not how much acid has been added.
Revise: Strong and Weak Acids
The production of charged particles called ions. Nuclear radiation can ionise atoms by knocking electrons out of them.
Revise: Radioactive Decay and Radiation Types
