Preparation: It is prepared in a number of ways:
1. Pure carbon monoxide can be prepared in the laboratory by heating formic acid with concentrated H2SO4 at 370–4010 K.
2. By burning carbon in a limited supply of oxygen.
3. By heating carbon dioxide with coke.
4. By the reduction of oxides of metal with coke.
