Which ones can be dried with alkali lime, and which ones do not?
Unable:1) acidic substances do not work. For example, SO2, CO2.2) alkaline, but not reactive, such as the formation of ammonia complex, and some alkaline hydrolysis, such as sodium bicarbonate3) neutral lipids, proteins3) metallic gases are represented by alkalinity, such as sodium vapor
Can be used for drying the neutral gas such as oxygen, CO, NH3; not dry acidic gases, such as carbon dioxide, sulfur dioxide, the main component of soda lime is: NaoH, Ca (oH) 2, KOH, they will react with acid gas
Ammonia with alkali lime, concentrated sulfuric acid can not, alkali lime is a mixture of NAOH and CAO, you can see whether the reaction
