    chemical reaction of Ca(OH)2

  • Ammonia

    The simplest test for nitrogen in organic compounds depends on the tendency of the compound to produce

  • Odor

    how to detect ammonia

  • Blue

    If ammonia is present, the red litmus paper will turn

  • Blue

    If ammonia is present, the blue litmus paper will turn

  • NH3 + H2O -- NH4+ +OH-

    Complete reaction of nitrogen

  • Sulfide ions

    The test for sulfur depends on producing

    The sulfide ions are then reacted with lead ions to give a

  • molybdate ions to produce a yellow precipitate

    Phosphate can be identified by their complex reaction with the

  • NaOH

    added to the ammonia as a strong base

  • 1 mL 0.1 M Lead Acetate

    mixed to the white albumin

  • Belstein test

    test that was conducted to the copper wire
