In the electrolysis cell used for the industrial preparation of Cl2 from aqueous NaCl, a diaphragm is used to separate the products. Give an equation for the reaction that would occur in the absence of the diaphragm and describe the nature of the reaction.
Homework Answers
At Anode :
2Cl- ----> Cl2 + 2e-
At cathode :
2H+ + 2e- ----> H2
In the absence of diaphragm
H2 + Cl2 ---> 2HCl [ Normal synthesis typre reaction ]
However there is another reactant which reacts with Cl2
NaOH + Cl2 ---> NaClO3 + NaCl
It is a disproportination reaction where Cl undergos oxidation and reduction .

Electrolysis
An industrial process referred to as the Downs cell converts molten sodium chloride into its constituent elements through electrolysis. The cell consists of a mixture (40%) of NaCl in CaCl2 (60%) at 600°C. Calcium ions do not participate in the reaction. The graphite anode is encircled by a steel cathode. Sodium floats over the denser electrolyte and is conveyed to a reservoir while chlorine gas escapes through a vertical pipe.[10]a. Identify the oxidizing and the reducing agent (1)b. Draw a...
