Carbon monoxide is conveniently produced in the laboratory by the dehydration of formic acid or oxalic acid, for example with concentrated sulfuric acid.[63][64][65] Another method is heating an intimate mixture of powdered zinc metal and calcium carbonate, which releases CO and leaves behind zinc oxide and calcium oxide:

 → ZnO + CaO + CO3Zn + CaCO

Silver nitrate and iodoform also afford carbon monoxide:

 + CO + 3AgI3O → 3HNO2 + H3 + 3AgNO3CHI
