A beaker with two chambers and a selectively permeable barrier contains sodium chloride (NaCl). Initially, the left side contains a low concentration of sodium chloride (NaCl) while the right side contains a high concentration. The barrier is permeable to chloride. At equilibrium what is the direction of the electrical driving force on chloride?

Assume you have a beaker with a selectively permeable barrier which only allows the movement of Ca2+ across the membrane. On the left side of the barrier you have a high concentration of CaCl2, while on the right side of the barrier you have a low concentration of  CaCl2.At the start, the electrical gradient for Ca+2 will be…
