Question

Molten sodium chloride decomposes to give sodium metal and chlorine gas when electric current is passed through it . Balance this equation​

Answer 1

Answer:

2NaCl------>2Na+Cl2

electric

current

Answer 2

Answer:

When current is passed through molten NaCl the following reactions take place:

When current is passed through molten NaCl the following reactions take place:Anode:

Cathode:

Na+e − →Na

Thus sodium is deposited at negative electrode (carhode) by undergoing reduction and chlorine is deposited to positive electrode (anode) by undergoing oxidation.
