Question

In the determination of transference numbers of HCl by moving boundary method a 0.10 M solution of HCl was taken in a cell having uniform area of cross section of 1.0 cm². At the end of experiment the boundary moved by 10.3 cm2 and 0.132 g of silver was deposited on the cathode of silver coulometer. Calculate the transference numbers of ions of HCl.
