A current of 0.42A is passed through a similar electrolytic cell set-up containing molten CaCl2 for 2.2 hours. Calcium metal is deposited at the cathode, and chlorine gas is generated and collected at the anode. Write the electrode reactions and calculate the amount of calcium metal (in grams) formed as well as the pressure of chlorine gas (in atm). Assume 330mL of gas was collected at 273K.
A constant current is passed through an electrolytic cell containing molten MgCl2 for 11.0 h. If 5.90 × 105 g of Cl2 are obtained, what is the current in amperes?
Elemental calcium is produced by the electrolysis of molten CaCl2. A) What mass of calcium can be produced by this process if a current of 6600 A is applied for 50 h?
