18. Solution to Chemistry Problem

2. When determining the cation transfer number in a 0.05 N silver nitrate solution by the Hittorf method, the current passed through the solution for such a long time that 55.3 mg of silver was deposited in a silver coulometer connected in series with the device. Titration of solutions from the anode compartment with a potassium dopantide solution showed that in this compartment the number of silver ion equivalents increased by 2.84*10-4. Accordingly, 2.84*10-4 equiv. of silver ion disappeared from the cathode compartment. Calculate the transfer number Ag.
