The cathode center and anode chambers of an electrolytic cell contain each 10 milliequivalents of HCl in aqueous solution. What will be the number of milliequivalents of HCl in each compartment after the passage of 5 milliequivalents of electricity through the cell? Assume that t+ is 0.80 and that H2 is given off at the cathode and Cl2 at the anode.
