Question Question 22
State why an aqueous solution of ammonia (NH4OH) is used for identifying cations.
The precipitate which are hydroxides of metallic radicals vary in :
- colour
- solubility in excess of NH4OH
Hence, ammonium hydroxide is used in qualitative analysis for identifying positive radicals or cations.
