TEST--54--XII [electro-]

Q .1.- Chlorine gas is an important industrial chemical produced by electrolysis. How many moles of electrons are required to prepare 1.000 metric ton (1000. kg) of chlorine gas by electrolysis of an aqueous solution of sodium chloride?

2 NaCl(aq) + 2 H₂O(l) -> 2 NaOH(aq) + H₂(g) + Cl₂(g)

How many faradays? How many coulombs? Assume that the efficiency of the electrochemical cell is 100%; that is, every electron involved results in the production of a chlorine atom.
