प्रश्न
Name the chloride of a metal which is soluble in excess of ammonium hydroxide. Write equation for the same.
उत्तर १
Zinc chloride (ZnCl2) is soluble in excess of ammonium hydroxide.
\[\ce{\underset{\text{colourless}}{ZnCl2} + 2NH4OH -> \underset{\text{white gelatinous ppt.}}{Zn(OH)2↓} + 2NH4Cl}\]
With excess of NH4OH ppt dissolves
\[\ce{Zn(OH)2 + 2NH4Cl + 2NH4OH(excess) -> \underset{\text{Tetrammine zinc(ll)chloride colourless}}{[Zn(NH3)4]Cl2 + 4H2O}}\]
उत्तर २
It is silver chloride [AgCl] dissolves in excess of NH4OH.
A product formed is [Ag(NH3)2]Cl [Soluble colourless Diamine Argentous (Z) chloride]
