Topics Covered (C5.8 – Strong & Weak Acids):
What “strong” and “weak” acids mean in chemistry.
Degree of ionisation and its link to H⁺ concentration.
Difference between strength and concentration (a major exam misconception).
How changes in H⁺ ion concentration affect pH.
Using the relationship:
pH changes by 1 for every 10× change in H⁺ ion concentration
pH changes by 1 for every 10× change in H⁺ ion concentration
Real-world examples: hydrochloric acid, nitric acid, ethanoic acid.
Exam-style explanation, calculation and reasoning tasks.
