How is the solubility of carbon dioxide gas in water increased?

Answer 1

Increasing the pressure. The relationship between CO2 and H2O is an equilibrium, by increasing the pressure the equilibrium shifts more to CO2 in aqueous phase. Think about a can of soda, it is pressurized on the inside, when you decrease the pressure by opening the can the CO2 is released, therefore by reversing the process the solubility can be increased.

Answer 2

The solubility of carbon dioxide (CO2) in water can be enhanced by lowering the water's temperature. Perhaps you've opened a bottle of soda/pop and not finished it right away, allowing it to warm up; then you notice it's not as "fizzy" as it was when it was colder. The CO2 has come out of solution and escaped into the air as the water rose in temperature.

The Earth has CO2 everywhere in the environment, from the Cliffs of Dover to the leaves of plants, but the single largest storehouse of this gas is the oceans. When the temperature of the planet increases, the ocean temperature rises (years later -- it takes quite a while) and so releases CO2. When the planet cools, the oceans absorb the CO2 again. It's part of the natural system that allows our planet to regulate itself.

Answer 3

Use temperature (or pressure), cold solutions hold more gas than hot solutions.

Also, in boiler and steam plants the carbon dioxide gas in the condensate lines, mixed with the hot water form carbonic acid that pits and corrodes the pipe, we add amines to help prevent the formation of carbonic acid. Amines can be derivitives of ammonia or sea weed. Old time boiler operators would add sea weed to the boiler.

Answer 4

If you want to increase the co2 level in water chill the water. Think of this as a soda. If it gets hot there is less "fizz" verses if it was chilled. I did check this answer with a test.

Answer 5

by increasing the pressure

Answer 6

make the water colder
