Zn(NO3)2 + 2 NH4OH -----------------------> Zn(OH)2 + 2 NH4NO3
white ppt.
on adding a little NH4OH we get white precipitate.
in excess of NH4OH
Zn(OH)2 + NH4OH -----------------------> [Zn(NH3)4]2+
colourless solution, soluble
on adding excess of NH4OH, Zn(OH)2 get dissolve in NH4OH and we get colourless solution.
