I have a homework to plan a practical for identifying ions.
There are numerous salts containing Na+, K+, Mg 2+ and Ba 2+. There is also one solution with an ammonium ion.
Is there any other way to test for the positive ions other than a flame test?
Also, Is it sensible for ammonium chloride to be on nichrome wire and in direct contact with a Bunsen flame or should I confirm the presence of the ammonium ion with NaOH and litmus paper first to avoid doing the flame test with ammonium.
