Talk:Soda lime

Here is a fun science fair project to do to test out Soda Lime:

Test different air samples for Carbon Dioxide and compare where the air is most "polluted." Use Soda Lime (Sodium Calcium Hydroxide) to test the amount of CO2 present in the air sample. (It will absorb the CO2--weigh the difference in weight before & after).

Hi, I'm wondering, where does soda lime come from? Is it mined from the earth or produced by a chemical process. Is more CO2 liberated in mining/producing soda lime than it would be capable of absorbing is used to mitigate CO2?

Mechanics
Can you provide more detail on the mechanism by which Soda Lime removes CO2? For example, does it simply retain it by adsorbtion, or is there a chemical reaction and if so what is the formula? —The preceding unsigned comment was added by 69.232.66.8 (talk) 05:28, 27 December 2006 (UTC).
