Question
Give one method for industrial preparation and one for laboratory preparation of CO and CO2 each.
Solution
Carbon monoxide (CO): Industrial preparation. It is formed by incomplete combustion of carbon in the limited air.
Laboratory preparation: Pure carbon monoxide is obtained by the dehydration of formic acid with concentrated H2SO4 at 373K.
Carbon dioxide:
Industrial preparation: It is prepared by burning carbon in excess of air or oxygen.
Laboratory preparation: It is prepared by the action of acids on carbonates:
