Consider the chemical equilibrium of the reaction. AgCl times s if and only if Ag raised to the plus A q power plus Cl raised to the negative A q power What will happen to the chemical equilibrium if AgNO sub 3 is added?

Adding AgNO₃ increases the concentration of Ag⁺ ions in the solution. By Le Châtelier’s principle, the equilibrium shifts to the left, using up some of the added Ag⁺ and Cl⁻ to form solid AgCl. Therefore, the system shifts toward the reactant side.
