💡 Exam Tips for Making Salts
🎯 Common Question Types:
- Describe the full method for making a named salt (4-6 marks)
- Explain the purpose of each step in the method (1-2 marks each)
- Identify whether a salt is soluble or insoluble and choose the correct method (1-2 marks)
- Write the equation for a precipitation reaction (2-3 marks)
- State solubility rules for specific ions (1 mark)
📝 Key Command Words:
- Describe the method: All steps in order — include equipment, quantities, safety where relevant
- Explain: Give a scientific reason for each step
- Suggest: Use solubility rules to predict what precipitate forms
- Write the equation: Include state symbols (aq), (s), (l), (g)
⚠️ Common Mistakes to Avoid:
- Boiling all the water off — only evaporate to concentrate, then let crystals form on cooling
- Adding excess acid instead of excess base — always add excess of the insoluble reactant
- Forgetting to wash the precipitate with distilled water to remove impurities
- Saying silver chloride is soluble — it is an insoluble white precipitate
- Not including state symbols in ionic precipitation equations
