Solutes and react to produce solutes and in a reversible reaction, as shown by the equation. In a solution at equilibrium, the concentrations of , , , and are , , , and respectively. When a small quantity of compound is added to this solution, the composition of the solution changes according to Le Chatelier’s principle.
