(a) Steady current of 2 amperes was passed through two electrolytic cells X and Y connected in series containing electrolytes and
untill 2.8g of Fe deposited at the cathode of cell X. How long did the current flow? Calculate the mass Zn deposited at the cathode of cell Y.
(molar mass : Fe = 56 g mol-1, Zn = 65.3 g mol-1, 1F = 96500C mol-1)
(b) In the plot of molar conductivity vs square root concentration
, following curves are obtained for two electrolytes A and B:
Answer the following:
(i) Predict the nature of electrolyte A and B.
(ii) What happens on extrapolation of to concentration approaching zero for electrolytes A and B?
