        • Reacting Carbonates with Dilute Acid
          • Forms
            • 1. Carbon dioxide
        • Instrumental Methods
          • Using standard laboratory equipment
      • Precipitation of Metal ions
        • Metal compounds in solution contain metal ions
          • Some form precipitates
            • insoluble solids that come out of solution when sodium hydroxide solution is added to them
          • sodium hydroxide + ammonium ions
            • ammonia gas given off
              • damp litmus paper turns blue

    • Saturated
      • organic compound stays brown
        • Bromine cant form a bond with saturated compound
      • Bromine water used to identify whether organic compound are saturated  or unstaturated
    • Unsaturated
      • Bromine water turns clear
      • Bromine water used to identify whether organic compound are saturated  or unstaturated
