    Without using indicators i thought that...

    You could react the solution supposidly containing ammonium ions with NaOH as that would form ammonia, and then react that with gaseous HCl to form a white smoke.

    Or does anyone know a simpler method?
    Any help appreciated.

    just test the ammonia gas given off using damp indicator paper. It is the only (common) alkaline gas..

    add a few drops of NaOH first to confirm no precipitate, then add NaOH in excess and either of the tests already suggested.
