How is carbon monoxide gas collected and purified?

Carbon monoxide gas is typically collected by generating it through reactions such as the incomplete combustion of carbon-containing materials or the reaction of acids with metals. It can be purified by passing the gas through a series of cleaning agents or scrubbing solutions, such as sodium hydroxide or potassium permanganate, which remove impurities and other gases. Additionally, fractional distillation can be employed when separating carbon monoxide from other gases in a mixture. Finally, proper storage in gas-tight containers ensures its stability and purity.
