Question

Give one method for industrial preparation and one for laboratory preparation of CO and $C{O}_2$ each.

Answer 1

Caron dioxide

In the laboratory, $C{O}_2$ can be prepared by the action of dilute hydrochloric acid on calcium carbonate. The reaction involved is as follows:

$C{O}_2$ is commercially prepared by heating limestone. The reaction involved is as follows:

Caron monoxide

In the laboratory, CO is prepared by the dehydration of formic acid with conc. $H_{2}S{O}_4$, at 373 K. The reaction involved is as follows:

CO is commercially prepared by passing steam over hot coke. The reaction involved is as follows:
