Frequently asked questions
- What topics are in O Level acids, bases and salts?
- The topic covers properties of acids and bases, pH and indicators, neutralisation reactions, salt preparation methods (precipitation, titration, excess metal), and simple titration calculations.
- How do I name salts from neutralisation?
- Salt name comes from the metal ion (or ammonium) from the base and the non-metal ion from the acid — e.g. HCl + NaOH → NaCl + water. Learn the patterns: sulfate from sulfuric acid, nitrate from nitric acid.
- What are common mistakes in acids and bases questions?
- Students confuse strength with concentration, pick the wrong indicator, or forget that ammonia forms ammonium salts not sodium salts. In titration questions, always write the balanced equation first.
