Solutions A and B are separated by a semipermeable membrane that is permeable to K+, but not to Cl-. Solution A is 100 mM KCI, and solution B is 1 mM KCI. Which of the following statements about solution A and solution B is true?
(A) K+ ions will diffuse from solution A to solution B until the [K+ ] of both solutions is 50.5 mM
(B) K+ ions will diffuse from solution B to solution A until the [K+ ] of both solutions is 50.5 mM
(C) KCl will diffuse from solution A to solution B until the [KCl] of both solutions is 50.5 mM
(D) K+ will diffuse from solution A to solution B until a membrane potential develops with solution A negative with respect to solution B
(E) K+ will diffuse from solution A to solution B until a membrane potential develops with solution A positive with respect to solution
