उत्तर
“An important use of decomposition reactions is in the extraction of metals from their naturally occurring compounds like chlorides or oxides.”
For Example:
When electricity is passed through molten sodium chloride, it decomposes to give pure sodium metal at the cathode.
\[\ce{\underset{(molten)}{2NaCl} ->[Electricity] \underset{Metal}{2Na} + Cl_{(g)}}\]
