  • Ion Testing
    • Carbonates
      • Add dilute hydrochloric acid
      • Bubble through lime water
        • Forms a cloudy precipitate of calcium hydroxide
      • Carbon dioxide forms when reacted with acid
        • Forms a cloudy precipitate of calcium hydroxide
    • Sulphates
      • Add hydrochloric acid and barium nitrate
      • White precipitate of barium sulphate forms
        • Insoluble
          • Differentiate between this and choride ions
    • Halides
      • Bromide
        • Forms a cream precipitate
        • Redissolves in concentrated ammonia
      • Add nitric acid and silver nitrate
      • Chloride
        • Forms a white precipitate
        • Redissolves in weak ammonia
      • Iodide
        • Forms a yellow precipitate
        • Doesn't redissolve
    • Ammonium
      • Warm and add sodium hydroxide
      • Litmus paper
        • Turns from red to blue
        • Must be damp for ammonia gas to dissolve
