- - - - CuSO4 + H2O = CuSO4 5 H2O
        
        The H2O in the molecule is known as the water of crystalization
- - - - chloride
        
        bromide
        
        iodide
        
        add dilute nitric acid (aq) then silver nitrate (aq)
        then add NH3 in excess
        
        chloride; White precipitate
        
        bromide; Cream precipitate
        
        iodide; Light yellow precipitate
    - - add barium chloride solution- a white precipitate will form
    - - Add HCL--> co2 gas will be emitted which will turn limewater cloudy
- - - - Oxygen
        
        When a splint just put out is exposed to oxygen it will relight
      - Hydrogen
        
        If the gas is hydrogen a bit would light and you'd hear a Pop
      - Carbon Dioxide
        
        A lit splint would go out
    - - ammonia
        
        Add sodium hydroxide to test tube, Add ammonium nitrate to test tube ,Light a Bunsen burner and damped litmus paper with water. Warm the solution in the test tube up with the burner and hold the litmus paper over the top
        
        If the litmus paper turns blue there is ammonia
      - Chlorine
        
        Get chlorine gas from the electrolysis of sodium chloride solution. Hold litmus paper over the bubbles and the chlorine gas should bleach it.
        
        The litmus paper goes from blue to white
- - - - Lithium; Bright red
