1. Chemistry of Acids GCSE Tutorial Your Name Date

2. What are Acids? - Substances that release hydrogen ions (H⁺) when dissolved in water. - Have a pH less than 7. - Examples: Hydrochloric acid (HCl), Sulfuric acid (H₂SO₄), Citric acid (found in citrus fruits).

3. Properties of Acids - Taste: Sour (e.g., lemon juice). - pH: Less than 7. - Conductivity: Conduct electricity in solution (electrolytes). - Reactivity: React with metals, bases, and carbonates.

4. Common Acids and Their Uses - Hydrochloric Acid (HCl): Used in stomach digestion, industrial cleaning. - Sulfuric Acid (H₂SO₄): Used in car batteries, manufacturing fertilizers. - Nitric Acid (HNO₃): Used in making fertilizers, explosives.

5. Acid-Base Reactions - Neutralization: Acid + Base → Salt + Water Example: HCl + NaOH → NaCl + H₂O - Indicators: Substances that change color to indicate pH. Example: Litmus paper, phenolphthalein.

6. Strong vs. Weak Acids - Strong Acids: Fully ionize in water (e.g., HCl, H₂SO₄). - Weak Acids: Partially ionize in water (e.g., acetic acid CH₃COOH).

7. The pH Scale - Ranges from 0 to 14. - 0-6: Acidic, 7: Neutral, 8-14: Basic. - Importance in everyday life: Food, soil, water quality.

8. Safety with Acids - Handling: Use gloves and goggles. - Storage: Store in labeled containers. - First Aid: Rinse with plenty of water if spilled on skin.

9. Summary - Acids are substances that release H⁺ ions in solution. - They have distinct properties and a variety of uses. - Understanding pH and acid-base reactions is essential. - Safety is crucial when handling acids.
