What substance does the SSR 90 use to chemically react with carbon dioxide?

The SSR 90 uses Sodium Bicarbonate to chemically react with carbon dioxide. This reaction is significant because Sodium Bicarbonate, commonly known as baking soda, has properties that allow it to effectively neutralize acids and absorb carbon dioxide. When sodium bicarbonate reacts with carbon dioxide, it forms sodium carbonate, water, and carbonic acid. This process is utilized in various applications, including mine rescue scenarios, to manage increased levels of carbon dioxide in the environment, ensuring the safety of personnel.

Calcium Hydroxide and Calcium Carbonate involve different chemical processes and are typically not the primary substances used for the intended reaction with carbon dioxide in the context of the SSR 90. Potassium Dioxide, while capable of interacting with other substances, does not specifically serve this purpose in standard carbon dioxide scrubbing applications. Thus, Sodium Bicarbonate stands out as the effective agent utilized for this chemical reaction.
