Why Does Soda Lime React with Carbon Dioxide?
Soda Lime Absorbs About 19% of Its Weight in Carbon Dioxide, Hence 100 G of Soda Lime Can Absorb Approximately 26 L of Carbon Dioxide. Some Carbon Dioxide May...

In this way, why does soda lime absorb carbon dioxide?
Soda lime is a mixture of NaOH & CaO chemicals, used in granular form in closed breathing environments, such as general anaesthesia, submarines, rebreathers and recompression chambers, to remove carbon dioxide from breathing gases to prevent CO2 retention and carbon dioxide poisoning.
Furthermore, does soda lime absorb carbon dioxide? Soda lime absorbs carbon dioxide and water vapour and deteriorates rapidly unless kept in airtight containers. Medically, soda lime is used to absorb carbon dioxide in basal metabolism tests and in rebreathing anesthesia systems. In gas masks it is an absorbent for toxic gases.
Accordingly, what happens when soda lime reacts with carbon dioxide?
Carbon dioxide and the water contained in the soda lime react to form carbonic acid: CO2 + H2O = H2CO3. In the second intermediate step, the carbonic acid reacts exothermically with sodium hydroxide to form sodium carbonate and water: H2CO3 + 2 NaOH = Na2CO3 + 2 H2O + heat.
Does lime absorb co2?
The process of making lime generates CO2, but adding the lime to seawater absorbs almost twice as much CO2. The overall process is therefore 'carbon negative'. Increasing absorption ability by just a few percent could dramatically increase CO2 uptake from the atmosphere.
