What is electrolysis ? Discuss electrolysis of molten electrolyte.

Text Solution

Verified by Experts

The process of chemical decomposition of an electrolyte (present in the molten or dissolved state) by passing an electric current is called electrolysis.
Electrolysis of molten NaCl
`2NaCl_((l))overset("Heat")hArr2Na^(+)+2Cl^(-)`
At cathode
`2Na^(+)+2eto2Na`
At anode
`2Cl^(-)-2eto2Cl`
`2Cl""toCl_(2)`
Sodium is prodụced at cathode and chlorine is produced at anode.
