$Ni$

Vedclass · Answer

(D) The process used for the purification of $Ni$ (Nickel) is known as Mond's process. In this process,impure nickel is heated in a stream of carbon monoxide $(CO)$ to form a volatile complex,nickel tetracarbonyl,$[Ni(CO)_4]$. The reaction is: $Ni(s) + 4CO(g) \xrightarrow{330-350 \ K} [Ni(CO)_4](g)$. This complex is then decomposed at a higher temperature to obtain pure nickel: $[Ni(CO)_4](g) \xrightarrow{450-470 \ K} Ni(s) + 4CO(g)$.
