State two relevant observations of the following:
Ammonium hydroxide solution is added to zinc nitrate solution in minimum quantities and then in excess
State two relevant observations for ammonium hydroxide solution is added to zinc nitrate solution slowly and then in excess.
उत्तर
- When \[\ce{NH4OH}\] is added to zinc nitrate solution in minimum quantity, it forms a gelatinous white precipitate.
- When added in excess, it dissolves to form a complex salt.
- A white gelatin-like precipitate is formed, which dissolves in excess of ammonium hydroxide.
