7. Solutions A and B are separated by a membrane that is permeable to Ca²+
and impermeable to CI. Solution A contains 10 mM CaCl2, and solution B
contains 1 mM CaCl₂. Assuming that 2.3 RT/F = 60 mV, Ca²+ will be at
electrochemical equilibrium when
(A) solution A is +60 mV
(B) solution A is +30 mV
(C) solution A is -60 mV
(D) solution A is -30 mV
(E) solution A is +120 mV
(F) solution A is -120 mV
(G) the Ca²+ concentrations of the two solutions are equal
