Chemical Properties of Akrosorb Soda Lime

The primary constituents of Soda Lime include:

Calcium Hydroxide – Ca(OH) 2

Water - H₂O

Sodium Hydroxide -  NaOH
 

Chemical Reactions which take place to bind CO₂

The general description of the reaction is as follows:

First the gaseous CO₂ reacts with water to form carbonic acid - H2CO3. Then the NaOH reacts with the carbonic acid to produce Na2CO3 and H₂O. The Na2CO3 reacts with the Ca(OH)2 that has been disassociated into Calcium and Hydroxide Ions.  (Ca++ and OH-) to produce CaC03 (calcium carbonate, otherwise known as limestone.) The CO₂ is now in a relatively stable state. There is a net production of three H₂O molecules for every molecule of CO₂ which is taken in.  Please Note that water is an important part of the reaction that takes place to bind the CO₂
