Soda lime Specification

Soda lime(CAS NO.8006-28-8) is generally a white to grayish white colored solid. Soda lime is the mixture of calcium hydroxide and sodium or potassium hydroxide, both corrosive materials. It is noncombustible and soluble in water with release of heat. And it is corrosive to metals and tissue.
The reaction between hydrogen sulfide and soda lime is attended with incandescence in the presence of air. In oxygen there is an explosion. Mixtures of barium oxide with mercurous or nickel oxide also react vigorously with hydrogen sulfide in air. Explosions may result.  Soda lime is made by treating slaked lime with concentrated sodium hydroxide solution.

Uses of Soda lime: Soda lime is a mixture of 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.

When you are using this chemical, please be cautious about it as the following:
1. In case of contact with eyes, rinse immediately with plenty of water and seek medical advice;
2. Wear suitable protective clothing, gloves and eye/face protection;
3. In case of accident or if you feel unwell, seek medical advice immediately (show label where possible);

You can still convert the following datas into molecular structure:
