If the concentration of ions in a solution is increased, how does this affect the reaction quotient (Q) and the equilibrium state?

• A. Q increases, and the system may shift to form more reactants.
• B. Q decreases, and the system shifts to form more reactants.
• C. Q decreases, and the system shifts to form more products.
• D. Q remains constant, and the system stays at equilibrium.

Answer: (A)
