$Ni$

Vedclass · Answer

(D) The process used for the refining of $Ni$ is known as the $Mond$ process.In this process,impure nickel is heated in a stream of carbon monoxide $(CO)$ at $330-350 \ K$ to form a volatile complex,nickel tetracarbonyl,$Ni(CO)_4$.This complex is then decomposed at a higher temperature $(450-470 \ K)$ to obtain pure nickel.The chemical reactions are:$Ni(s) + 4CO(g) \rightarrow Ni(CO)_4(g)$$Ni(CO)_4(g) \rightarrow Ni(s) + 4CO(g)$
