Why is an electric current needed to form sodium and chlorine from the sodium chloride solution?

This may be a trick question, electrolyis of a sodium chloride solution produces chlorine at the anode but does not produce sodium at the cathode. Electrolysis of molten sodium chloride does however produce sodium and chlorine.


What is decomposition of AgCl?

Decomposition of sodium chloride by electrolysis:- in water solution: 2 NaCl + 2 H2O = 2 NaOH + H2 + Cl2- molten sodium chloride: 2 NaCl----------->2 Na + Cl2


Where does molten carbonate come from?

Sodium carbonate can be made by the Solvay process from brine (sodium chloride) and limestone (calcium carbonate). In the US there are large deposits of a mineral called Trona which is sodium bicarbonate carbonate, and it is obtained from that. Potassium carbonate is made by electrolysis of potassium chloride which is found as mineral Sylvite, which gives potassium hydroxide which is then carbonated with CO2. See wikipedia entries for Solvay Process, Trona, and Potassium Carbonate


Why does molten sodium chloride conduct electricity but crystalline magnesium chloride does not?

In the molten state the ions of sodium chloride are free to move. Magnesium chloride would also conduct if it were molten. Since the ions of the magnesium chloride are bound together in the crystal lattice they cannot carry a current.


Why is hydrogen collected at cathode instead of sodium during the electrolysis of sodium chloride?

When an aqueous solution of sodium hydroxide is electrolyzed, hydrogen is produced at the cathode because hydrogen can be produced at a lower voltage than can sodium, and the supply of hydrogen from the water of the solution is sufficient to consume all the current supplied. When molten sodium chloride is electrolyzed, however, sodium is produced at the cathode.
