So the electrochemical gradient basically combines these two different types of gradients. So notice that in this case, we also had a concentration gradient because we have no molecule C on the right side. All the molecules C were on this side. So on top of these molecules moving to the right side as a result of an electric gradient, because there is an attraction between the positive and negative, these C molecules will also move to the right side because they will move from a high C concentration to a low C concentration. So this concept, this scenario actually incorporates both the concentration gradient and our electrical gradient. So at the end, we have an even amount of molecules on both sides, and the charges are also in equilibrium.
