Using Le Châtelier's principle, explain how the addition ofaqueous ammonia dissolves silver chloride. If HNO3 isadded after the AgCl has dissolved in the NH3solution,it causes AgCl to re-precipitate. Explain by selecting all truestatements.
1.) AgCl is an insoluble solid.
2.) Ag+reacts with NH3 to formAg(NH3)2+, which \"adds\"Ag+ to the AgCl equilibrium, causing more AgCl todissolve.
3.) Ag+reacts with NH3 to formAg(NH3)2+, which \"removes\"Ag+ from the AgCl equilibrium, causing more AgCl todissolve.
4.) Adding HNO3, a strong acid, destroys the complexion and \"removes\" Ag+ from the AgCl equilibrium, causingAgCl(s) to re-form.
5.) Adding HNO3, a strong acid, destroys the complexion and \"adds\" Ag+ to the AgCl equilibrium, causingAgCl(s) to re-form.
6.) None of these.
