Question

consider the chemical equilibrium of the reaction. agcl(s) ⇌ ag⁺(aq) + cl⁻(aq) what will happen to the chemical equilibrium if agno₃ is added? there is no shift in the chemical equilibrium of the system. the chemical equilibrium of the system shifts to the right. the chemical equilibrium of the system shifts to the left. the chemical equilibrium of the system is destroyed.

Explanation:

1. First, analyze the reaction: $\ce{AgCl(s)

ightleftharpoons Ag^{+}(aq) + Cl^{-}(aq)}$.

1. When $\ce{AgNO_{3}}$ is added, $\ce{AgNO_{3}}$ dissociates in solution to produce $\ce{Ag^{+}}$ ions (since $\ce{AgNO_{3}(aq) -> Ag^{+}(aq) + NO_{3}^{-}(aq)}$).
2. According to Le Chatelier's principle, when the concentration of a product ($\ce{Ag^{+}}$ in this case) is increased, the equilibrium will shift in the direction that consumes the added substance.
3. So, the equilibrium of the $\ce{AgCl}$ dissolution reaction will shift to the left (towards the reactant, $\ce{AgCl(s)}$) to consume the excess $\ce{Ag^{+}}$ ions. Also, chemical equilibrium is a dynamic state and is not destroyed by changes in concentration; it just shifts to re - establish equilibrium.

Answer:

The chemical equilibrium of the system shifts to the left.
