Metallic sodium can be made by the electrolysis of molten NaCl. (a) What mass of Na is formed by passing a current of 9.02 A through molten NaCl for 1.60 days? The unbalanced chemical reaction representing this electrolysis is shown below. NaCl Na + Cl2 g of Na is formed by this electrolysis. (b) How many minutes are needed to plate out 6.00 g of Na from molten NaCl using 9.49 A current? minutes are needed.

Molten salts When electricity is applied to a molten binary salt, the cation will be reduced and the anion will be oxidized. The electrolysis of CaBrz (), for example, produces Ca(s) at the cathode (from the reduction of Ca2+) and Br2(1) at the anode (from the oxidation of Br"). If more than one cation is present, only the one with highest reduction potential will be reduced. Similarly, if more than one anion is present, only the one with the highest...
