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 KCl 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?
A)The concentration of Na⁺ in A will be higher than it was at time zero.
B)Diffusion of K⁺ from A to B will be greater than the diffusion of K⁺ from B to A.
C)There will be a potential difference across the membrane,with side B negative relative to side A.
D)The electrical potential difference and diffusion potential due to the concentration gradient for K⁺ will be equal in magnitude and opposite in direction.
E)The concentration of Cl⁻ will be higher in B than it was at time zero.
