Soda asbestos is primarily used in laboratory settings for the absorption of carbon dioxide. It is commonly employed in gas analysis and purification processes where the removal of CO₂ is essential. In organic chemistry, it is utilized in drying tubes to prevent moisture and CO₂ from interfering with sensitive reactions. Additionally, it finds application in closed-system environments, such as submarines and spacecraft, to maintain breathable air by scrubbing CO₂ from the atmosphere. Its high efficiency in absorbing carbon dioxide makes it a valuable component in various scientific and industrial applications.
