It is easy to absorb carbon dioxide and water in the air, but the absorption capacity is slightly worse than NaOH and KOH. Lithium hydroxide has the property of a base, and the following reaction can occur.
1. Alkaline reaction can make the purple litmus test solution turn blue, make the colorless phenolphthalein test solution turn red; and the concentrated solution can be experimentally verified, the phenolphthalein can be denatured, and the solution changes from red to colorless (similar to concentrated NaOH) ).
2. Neutralize HCl+LiOH=LiCl+H2O with acid
3. React with acidic oxides 2LiOH+CO2=Li2CO3+H2O (this reaction is used to absorb carbon dioxide in aerospace)
4. Reaction with metal salt solution FeCl3+3LiOH=Fe(OH)3↓+3LiCl
Lithium hydroxide can be used as a developing agent and lubricating oil for spectroscopic analysis. The additive of alkaline battery electrolyte can increase the electric capacity by 12%~15% and increase the service life by 2~3 times.
It can be used as an absorbent for carbon dioxide to purify the air inside the submarine.
The chemical equation is: 2LiOH(s) + CO2(g) = Li2CO3(s) + H2O(l).
Used in the production of lithium salt and lithium grease, alkaline battery electrolyte, lithium bromide refrigerator absorption liquid, lithium soap (lithium soap), lithium salt, developer, etc. or as analytical reagents; petroleum, chemical, light industry, Used in the nuclear industry. When used in alkaline storage batteries, the aluminum content is not more than 0.06%, and the lead content is not more than 0.01%. Used as an analytical reagent, photographic developer, also used in the manufacture of lithium; used as a raw material for the preparation of lithium compounds. Can also be used in metallurgy, petroleum, glass, ceramics and other industries.
