Tests for negative ions
  1. Carbonate ions
    1. Add dilute hydrochloric acid to the substance to see if it fizzes. If it does and the gas turns limewater milky, the substance contains carbonate ions.
    2. Halide ions
      1. Add dilute nitric acid and then silver nitrate solution
        1. Chloride ions: White precipitate
          1. Bromide ions: Cream precipitate
            1. Iodide ions: Yellow precipitate
          2. Sulfate ions
            1. Add dilute hydrochloric acid and then barium chloride solution.
              1. If a white precipitate forms, sulfate ions are present.
