(a) State Kohlrausch law of independent migration of ions. Write an expression for the molar conductivity of acetic acid at infinite dilution according to Kohlrausch law. (b) Calculate m for acetic acid. Given that 0m (HCl) = 426 S cm2 mol-1 0m (NaCl) = 126 S cm2 mol-1 0m (CH3COONa) = 91 S cm2 mol-1 Or (a) Write the anode and cathode reactions and the overall reaction occurring in a lead storage battery. (b) A copper-silver cell is set up. The copper ion concentration is 0.10 M. The concentration of silver ion is not known. The cell potential when measured was 0.422 V. Determine the concentration of silver ions in the cell. (Given E0Ag+/Ag = +0.80 V, E0Cu2+/Cu=+0.34V)
