Questions
1. A sohution of 100 mmol/L KCI is separated from a solution of 10 mmol/L Ka by a membrane that
Is very permeable to K lons, but impermeable to C lons. What are the magnitude and the direc-
tion (sign) of the potential difference that will be generated across this membranet (Assume that
2.3 RT/F-60 mV.) Will the concentration of K in either solution change as a result of the process
that generates this potential difference?
2 Irthe same solutions of KCl described in Question I are now separated by a membrane that is very
permeable to Cr ions, but impermeable to K lons, what are the magnitude and the sign of the
potential difference that is generated across the membrane?
