Which of the following is a method of preparation of CO?
Which of the following is a method of preparation of CO?
CO can be prepared by heating potassium ferrocyanide with conc. 
By dehydration of formic acid with conc. 
at 373 K
The correct options are
A CO can be prepared by heating potassium ferrocyanide with conc.
B By heating oxides of heavy metals
C By passing steam over red hot coke
D By dehydration of formic acid with conc. at 373 K
Corbon monoxide can be prepared by various different methods. 1. By incomplete combustion of carbon and carbon containing fuels or direct oxidation of carbon in limited supply of air or oxygen.
2C+O2→2CO
2. By heating oxides of heavy metals, e.g. iron, zinc etc. with carbon.
Fe2O3+3C→2Fe+3CO
ZnO+C→Zn+CO
3. In the laboratory, pure CO is prepared by dehydration of formic acid (HCOOH) with conc. H2SO4 at 373 K.
HCOOHH2SO4−−−−→CO +H2O
Formic acid 373K Carbon Monoxide
(H2SO4 acts as a dehydrating agent)
4. In the laboratory, CO can be prepared by heating potassium ferrocyanide, K4[Fe(CN)6], with conc H2SO4.
5. Commercially, CO is produced by passing steam over red hot coke.
C(s)+H2O(g)473−1273 K−−−−−−−→CO(g)+H2(g)Water Gas
