a concentration cell has Fe(NO3)2 on two sides of a semi permeable membrane. On one side, the iron nitrate concentration is 250 mM and on the other side the concentration is 25 uM. What is the electric potential generated by this cell? And which side is the "anode", and which side is the "cathode"?
