Compartments A and B are separated by a membrane that is permeable to K+ but not to Na+ or Cl. At time zero, a solution of KCI is poured into compartment A and an equally concentrated solution of NaCl is poured into compartment B. Which would be true once equilibrium is reached? The concentration of Na+ in A will be higher than it was at time zero. The electrical and chemical gradients across the membrane for K+ will be equal in magnitude and opposite in direction. The concentration of K+ will be equal in both chambers. Side B will have a negative charge relative to side A. Diffusion of K+ from A to B will be greater than the diffusion of K+ from B to A.
