Using Le ChÃ¢telier'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.
