Can Sodium Hydroxide Effectively Capture and Release CO2 from the Atmosphere?

In summary, it is possible to obtain carbon dioxide by passing air through a mist of sodium hydroxide solution, where it is absorbed and forms sodium carbonate. This solution is then pumped into an electrolysis cell and an electric current is passed through it, resulting in the release of carbon dioxide which can be collected and stored. However, this technology has been discussed before and it may be more efficient and cost-effective to use fermentation to capture and sell carbon dioxide.

I was thinking how it is possible to obtain carbon dioxide capturing it from the atmosphere and releasing it from the solution.
I've read that "air meets a mist of a sodium hydroxide solution...the carbon dioxide is absorbed by reaction to form sodium carbonate...this solution is pumped into an electrolysis cell through which an electric current is passed. The electricity results in the realease of the carbon dioxide which is collected and stored..."

So all is based to pass air to the sodium hydroxide solution and that solution will capture co2?
Then... I add current with steel electrodes and the CO2 from the sodium carbonate solution will be released?

Lot faster and cheaper to use fermentation. Many larger whisky and beer makers clean and sell it. Get a plastic coke bottle, water, sugar, yeast and a bit of nutrient salts.
 

1. What is the purpose of using CO2 from Sodium hydroxide in scientific experiments?

The purpose of using CO2 from Sodium hydroxide in scientific experiments is to study the chemical reactions and properties of CO2. Sodium hydroxide is used as a source of CO2 because it readily reacts with CO2 to form sodium carbonate, which can then be studied.

2. How is CO2 from Sodium hydroxide produced?

CO2 from Sodium hydroxide is produced through a process called carbonation. This involves passing CO2 gas through a solution of Sodium hydroxide, resulting in the formation of sodium carbonate and water.

3. Can CO2 from Sodium hydroxide be harmful to the environment?

CO2 from Sodium hydroxide can be harmful to the environment if released in large quantities. This is because CO2 is a greenhouse gas that contributes to global warming and can also cause acidification of water bodies.

4. How is CO2 from Sodium hydroxide used in industrial processes?

CO2 from Sodium hydroxide is used in various industrial processes, including the production of sodium bicarbonate, which is used in baking and as a cleaning agent. It is also used in the manufacture of glass and paper, and as a pH regulator in water treatment.

5. Can CO2 from Sodium hydroxide be used as a carbon source for plants?

No, CO2 from Sodium hydroxide cannot be used as a carbon source for plants. This is because the CO2 produced through carbonation is in the form of sodium carbonate, which is not a form of carbon that can be utilized by plants for photosynthesis. Plants require CO2 in its gaseous form to carry out photosynthesis.
