Key Topics to Revise

1

Acid-Base Indicators

  • Indicators are substances that show different colors in acidic and basic solutions
  • Natural indicators: Litmus (from lichen), turmeric, red cabbage extract, flower petals
  • Synthetic indicators: Methyl orange, phenolphthalein
2

Chemical Properties of Acids and Bases

  • Acids react with metals to produce salt + hydrogen gas
  • Bases react with metals to produce salt + hydrogen gas
  • Acids react with metal carbonates/bicarbonates to produce salt + CO₂ + water
3

Acids and Bases in Aqueous Solution

  • Acids produce H⁺ ions in aqueous solution
  • Bases produce OH⁻ ions in aqueous solution
  • H⁺ ions cannot exist alone, they combine with H₂O to form H₃O⁺ (hydronium ions)
4

Strength of Acids and Bases

  • Strong acids produce more H₃O⁺ ions (HCl, H₂SO₄, HNO₃)
  • Weak acids produce fewer H₃O⁺ ions (CH₃COOH)
  • Strong bases produce more OH⁻ ions (NaOH, KOH)
