That's not necessary. NaCl is completely dissociated, so you only need to consider the initial concentration of Cl- in the solution.Not a Wrench said:
Chemical equilibrium is the state in which the forward and reverse reactions of a chemical reaction occur at the same rate, resulting in a constant concentration of reactants and products.
Equilibrium is reached when the rate of the forward reaction is equal to the rate of the reverse reaction. This can be achieved by changing the concentration, temperature, or pressure of the system.
The concentration of reactants and products, temperature, and pressure can all affect the position of equilibrium in a chemical reaction. Changes in these factors can shift the equilibrium in either the forward or reverse direction.
Le Chatelier's principle states that when a system at equilibrium is subjected to a stress, it will shift in the direction that reduces the stress. This can be applied to chemical equilibrium by predicting how changes in concentration, temperature, or pressure will affect the equilibrium position.
Chemical equilibrium is important in many processes, such as in the production of fertilizers, pharmaceuticals, and food. Understanding and controlling equilibrium allows us to optimize these processes for maximum efficiency and yield.
