Through a solution containing 34.69 mmol tetramethylammonium picrate per kg of solution, a current was sent for 1 h 50 min between a Ag anode and a Ag/AgCl cathode. The solution was then divided into three parts: anode, middle, and cathode solution. The anode solution weighed 31.238 g and contained 42.36 mmol picrate ion per kg; the cathode solution weighed 46.065 g and contained 29.51 mmol picrate ion per kg. The middle solution still contained 34.69 mmol tetramethylammonium picrate per kg of solution and no other kinds of ions. In a coulometer, connected in series, 63.41 mg silver had simultaneously precipitated. The organic ions do not react in this process. Find the transference number of the cation at the temperature of the experiment.,
