How do silver ions interact with halide ions? How can the presence of ammonium in aqueous solution be evidenced?
Of course, the equation presupposed the ABSENCE of other metal ions that form insoluble halides, i.e. we assume the absence of
For ammonium ions, we could exploit the acid-base properties of ammonium cation:
The odour of ammonia is unmistakable. Ammonium forms an insoluble tetraphenylborate,
