Chemistry

(b) A vessel separated into two parts, A and B, by a bilayerlipid membrane contained an aqueous solution of KCl withconcentration 0.01 mol L-1 in part A and 0.1 mol L-1 in part B andof NaCl with concentration 0.1 mol L-1 in part A and 0.01 mol L-1in part B. The membrane included potassium channels, which made itpermeable for K+ ions. The temperature of the vessel was kept at 30o C. (i) Calculate the electrical potential between the two sidesof the membrane (membrane potential). (ii) Explain how an increaseof temperature and an addition of NaCl to part B will affect themembrane potential. Assume ideal behaviour of the solutions.
