KCl solutions separated by a membrane in The K+ and Cl– ions will permeate the membrane independently as they diffuse down their respective gradients of electrochemical potential, In biological systems, membranes are usually more permeable to K+ than to Cl–. Therefore, K+ will diffuse out of the cell faster than Cl–, causing
