Is carbon monoxide a acid or alkaline solution?

Answer 1

CO2 + H2O = H2CO3 (Carbonic Acid).

NB The cooler a liquid the more gas it will hold in solution.

Conversely the warmer a liquid the less gas it holds in solution. This second statement is evidenced by boiling water. As the water warms up small bubbles begin to rise. As the liquid becomes hotter the bubbles become larger and more violent. This is the gas held in solution leaving the solution.

Answer 2

First of all, Carbon Monoxide is a gas, not a solution. To find the acidity or alkalinity of a solution [the 'potential of hydrogen or the 'ph'] there has to be hydrogen present, which you do not have in CO, carbon monoxide. The first answer above needs a bit of clarification. Gasses often dissolve in liquid solvents to form solutions. Well known examples include Ammonia-Water, Chlorine-Water, Carbon Dioxide-Water, and Nitrogen Dioxide-Water. The amount of gas held in the solution depends on temperature, pressure, and sometimes, the presence of other chemicals (cosolvents or catalysts). Carbon monoxide (CO) also dissolves in water, though not as well as carbon dioxide (CO2). When CO dissolves in water, some amount of formic acid (HCOOH) is produced; the solution is thus weakly acidic. There are at least two industrial processes known to this writer that involve dissolving CO in water. In one, CO is dissolved in water to make an antibacterial rinse for meat processing. In the other, CO is dissolved in water for the express purpose of manufacturing formic acid. (Industrially, this reaction occurs at elevated temperature and pressure in the presence of an amine. At room temperature, this reaction is energetically not very favorable.) See US Patent 5,334,759 (1994).

Answer 3

The carbon monoxide (CO) is practically insoluble in water.

Answer 4

Carbon dioxide dissolves in water to form carbonic acid. We drink carbonic acid when we drink soda pop/ soft drink.

CO2 + H2O --> H2CO3
