Question

Explain the role of co in the extraction of nickel

Answer 1

The Mond process, sometimes known as the carbonyl process, is a technique created by Ludwig Mond in 1890, to extract and purify nickel. ... The impure nickel reacts with carbon monoxide at 50–60 °C to form the gas nickel carbonyl, leaving the impurities as solids. Ni(s) + 4 CO(g) → Ni(CO)4(g) 3.

Answer 2

In the extraction of Nickel or Ni, there is a very important role of CO.

The role is given below -

The CO serves as an agent to reduce or as an reducing agent. So as CO is an reducing agent, it helps to reduce the ore of iron to reduce into the iron metal.

This is done by the method called Mond's method.
