    I want to test a compound to check what halides are present i.e chloride, bromide and iodide ions.

    I have the following reagents that I can use:

    Aqueous barium nitrate

    Aqueous Bromine

    Aqueous silver nitrate

    Aqueous sodium carbonate

    Concentrated ammonia solution

    Dilute hydrochloric acid

    Dilute sodium hydroxide Solution

    Hexane


    I know that silver nitrate and ammonia can be used, but what other methods are there using the above reagents?

    Thanks in advance

    Most of these other reagents are used to test for other functional groups and ions. I only know of silver nitrate and ammonia being used to test for halides

    How does nitric acid help in identifying the halides?

    see if it converts to an alkene under a reaction of a strong base (KOH) aqueous in ethanol with an elimination reaction....???

    It removes unwanted ions which could form a precipitate and give a false result
