Chapter 20, Problem 20.94(choose chapter or problem)
Elemental calcium is produced by the electrolysis of molten \(\mathrm{CaCl}_{2}\).
(a) What mass of calcium can be produced by this process if a current of \(7.5 \times 10^{3} \mathrm{~A}\) is applied for 48 h? Assume that the electrolytic cell is 68 % efficient.
(b) What is the minimum voltage needed to cause the electrolysis?
