How Does a Potassium Hydroxide Solution Remove Carbon Dioxide from Air?
What is the process by which a potassium hydroxide solution removes carbon dioxide from air?
The process by which a potassium hydroxide solution removes carbon dioxide from air involves a chemical reaction between the potassium hydroxide and the carbon dioxide present in the air.
Potassium hydroxide is a strong base that is commonly used to remove carbon dioxide from air and other gases. When exposed to carbon dioxide, potassium hydroxide reacts with it to form potassium carbonate and water.
This reaction can be represented by the following chemical equation:
2KOH + CO2 → K2CO3 + H2O
The potassium carbonate that is formed is a solid that can be easily removed from the solution, leaving behind water and effectively removing the carbon dioxide from the air.
