Web2+. and NH. 3. Aqueous zinc +2 ion solution is colourless. When ammonia solution is added to the Zn +2 ion, different observations can be seen according to the amount of added ammonia or concentration of ammonia. This is an experiment in testing of zinc ion in qualitative analysis in chemistry. Assume that, aqueous Zn 2+ ion is associated with ... NH 3 + H 2 O NH+ 4 + OH −. In a 1 M ammonia solution, about 0.42% of the ammonia is converted to ammonium, equivalent to pH = 11.63 because [ NH+ 4 ] = 0.0042 M, [OH − ] = 0.0042 M, [NH 3 ] = 0.9958 M, and pH = 14 + log 10 [OH − ] = 11.62.
