The zinc chloride battery operates on the reaction Zn + Cl2 à ZnCl2. It has been suggested as a possibility for exploitation as a source of power for driving vehicles in that a bank of 118 such cells, connected in series, has a capacity of approximately 90 kW h.
(i) Calculate the standard e.m.f (voltage) of the cell, noting the following standard electrode potentials.
(ii) Calculate the mass of solid chlorine hydrate (Cl12 8H2O) which must be stored in the bank in order to sustain power capacity. Compare this with the amount of Cl2 required.
Explain a sample is a mixture of the salts and silver nitrate, copper (II) chloride, and iron (III) chloride. Define when a 1.000 g sample of the mixture is dissolved in water as well as reacted with excess silver nitrate, 1.7809 g of precipitate ..
