What should be the considerations during the extraction of metals by electrochemical method?
(N/A) $i$. Reactivity of the metal: The metals should be extracted by electrolysis of their fused salts if the metals are highly reactive,as they may react with water during the reaction.
$ii$. Nature of electrodes: The electrodes used for electrolysis should not react with the products of electrolysis. If they do react,the electrodes must be made of a material that is inexpensive,as their periodic replacement should not exceed the cost of the process.
