Carbon monoxide is not an acidic oxide (it differs from carbon dioxide in that regard) and is only slightly soluble in water.
Carbon dioxide is a colorless and odorless gas. Unlike carbon monoxide, CO2 is nontoxic. It is an acidic oxide
Carbon dioxide is used in beverages, in fire extinguishers, and in the manufacture of baking soda, NaHCO3, and soda ash, NaCO3. Solid carbon dioxide, called dry ice, is used as a refrigerant. Dry ice is also used in cloud seeding to induce rain
