New cards

carbonate test

  1. in a test tube add dilute nitric acid to solid/solution being tested

  2. if bubbles are produced this could be CO2

  3. bubble the gas produced through lime water

  4. Observe if white ppt forms

    CO2 + Ca(OH)2 → CaCO3 (s) + H2O

2
New cards

sulfate test

  1. add Barium Nitrate to solution and observe if a dense white ppt forms

    Ba2+ + SO4 2- → BaSO4 (s)

3
New cards

halide test

  1. add aq AgNO3 to aq halide solution

  2. silver halide ppt are different colours

  3. add aq ammonia to test solubility

    Cl- soluble in dilute NH3

    Br- soluble in conc NH3

    I- insoluble in conc NH3

New cards

ammonium ion test

  1. add aq NaOH to the solution of an ammonium ion

  2. ammonia gas if produced

  3. ammonia is alkaline and will turn a moist pH indicator paper blue
