Stoichiometry of Electrolytic Reactions — Faraday's Law
A chlor-alkali electrolytic cell is used in the industrial production of chlorine gas and caustic soda (NaOH). Electric current is passed through brine (a solution of NaCl in water), resulting in the formation of chlorine and hydrogen gas, as well as NaOH. What volume of Cl will be formed by a 1.5A current in such a cell, over the course of 1 hour (at standard temperature and pressure)? Start by writing down a balanced chemical equation for this oxidation-reduction process. You will need to look up the charge of a mol of electrons and the volume of a mol of gas.
