Ammonium hydroxide.
This reaction takes place in two stages.
1. If a little aqueous ammonia solution is added to zinc chloride a white precipitate of zinc hydroxide forms.
ZnCl2 + 2NH4OH -----> Zn(OH)2(s) + 2NH4Cl
Zinc hydroxide(White ppt.)
2. If more ammonia is added, then the precipitated zinc hydroxide redissolves to a colourless solution of a soluble zinc ammine, a complex ion.
Zn(OH)2(s) + 2NH4OH + 2NH4Cl --------> [Zn(NH3)4] Cl2 + 4H2O
Tetrammine Zinc chloride
