Answer to Question #132908 in General Chemistry for Van Sung

Question

Solution, reagent, observation and conclusion for test solution Cu(NO3)2(aq), AgNO3 (aq), Zn(NO3)2 (aq)
1 mL 6 M NH3 added
1 drop 6 M HCI

Answer 1

1)Silver nitrate react with ammonia and Hydrochloric acid:

NH₃ + HCl = NH₄Cl

NH₄Cl + AgNO₃=NH₄NO₃ + AgCl

Both reactant ammonium chloride and silver nitrate are in soluble form but the product formed in the above reaction in which ammonium nitrate are also in soluble form but silver chloride are insoluble form.

(2) Ammonium Chloride react with ammonia and HCl

2NH₄Cl + Zn(NO₃)₂=2NH₄N₄NO₃ + ZnCl₂

Ammonium Chloride + zinc Nitrate=ammonium nitrate+ zinc + Chloride.

3) Copper nitrate react with ammonia and HCl:

2NH₄Cl + Cu(NO₃)₂=2NH₄NO₃ + CuCl₂

Ammonium chloride + Copper nitrate = ammonium nitrate + Copper Chloride
