Neutralization_Lesson_Refined_PPT.pptx grade 12
- 1. Lesson: Neutralization Acids +Bases → Salt + Water
- 2. Introduction to Neutralization •- Neutralization = reaction of acid + base • - General result → salt + water • - Everyday importance: medicine, agriculture, cleaning
- 3. Acid + Base→ Salt + Water • - Word equation: Acid + Base → Salt + Water • - Example: HCl + NaOH → NaCl + H₂O • - Strong vs. weak acids/bases affect reaction strength and completeness
- 4. Neutralization in DailyLife • - Medicine: antacids relieve stomach acidity • - Agriculture: lime neutralizes acidic soils • - Environment: treating acidic wastewater before disposal
- 5. Titration as Neutralization •- Titration = technique to find unknown concentration • - Equivalence point: acid and base fully neutralize • - Indicators: phenolphthalein, methyl orange • - Example: NaOH titrated with HCl
- 6. Salts from Neutralization •- Salt type depends on acid and base used • - Examples: NaCl, KNO₃, CaSO₄ • - Properties: solubility, hydrolysis possible
- 7. Buffer Solutions • -Formed by partial neutralization of weak acids/bases • - Buffers resist sudden pH changes • - Applications: blood pH regulation, industrial processes
- 8. Summary & Takeaways •- Neutralization: Acid + Base → Salt + Water • - Essential in health, agriculture, industry • - Titration and buffers are practical applications • - Central concept: balance and control of pH
