    Part I

    5 x 2 = 10

  1. Define anode and cathode

  2. Why does conductivity of a solution decrease on dilution of the solution.

  3. State Kohlrausch Law. How is it useful to determine the molar conductivity of weak electrolyte at infinite dilution.

  4. Describe the electrolysis of molten NaCl using inert electrodes

  5. The resistance of a conductivity cell is measured as 190 Ω using 0.1M KCl solution (specific conductance of 0.1M KCl is 1.3 Sm-1). When the same cell is filled with 0.003 M sodium chloride solution, the measured resistance is 6.3KΩ. Both these measurements are made at a particular temperature. Calculate the specific and molar conductance of NaCl solution.
