Tests
Halide compounds such as KCl, KBr and KI can be tested with silver nitrate solution, AgNO3. The halogen will react with Ag+ and form a precipitate, with varying colour depending on the halogen:
- AgF: No Precipitate
- AgCl: White
- AgBr: Creamy (Pale Yellow)
- AgI: Green (Yellow)
For organic compounds containing halides, the Beilstein test is used.

Famous quotes containing the word tests:
“Every perversion has survived many tests of its capabilities.”
—Mason Cooley (b. 1927)
“The secret of a leader lies in the tests he has faced over the whole course of his life and the habit of action he develops in meeting those tests.”
—Gail Sheehy (b. 1937)
“It is not the literal past that rules us, save, possibly, in a biological sense. It is images of the past.... Each new historical era mirrors itself in the picture and active mythology of its past or of a past borrowed from other cultures. It tests its sense of identity, of regress or new achievement against that past.”
—George Steiner (b. 1929)
