Solution Conductivity 1. A Conductivity Cell, has a resistance of 747.5 when filled with 0.01 M KCI solution and its resistance is 876 when it is filled with 0.005 M solution of CaCl2, both of which took place at 250C. Calculate the conductance specific for CaCl2 solution. 2. In the Hittorf method to determine the transport number of H+ and Cl- ions, 0.01 M HCI solution is electrolyzed with Ag, at the anode AgCl according to the reaction; Ag + Cl- y AgCl(s) + e and platinum cathode, according to the reaction: H+ + e ÿ 1/2H2 to produce hydrogen gas. To pass 21.6 Coulomb of charge, the amount of HCI in the solution around the anode decreases by 0.00185 mol, and the amount of HCI in the solution around the cathode increases by the same amount. Determine the transport numbers of the H+ and Cl- ions. 3. Determine the solubility of the slightly soluble AgCl salt if the specific conductance of the saturated solution at 250C is 2.28 x 10-4 -1m-1, after deducting the specific conductance of the water itself.
