 0.17 percent, at 15° C. (59° F.), and diminishing as the temperature rises. 



Properties. — A clear, colorless liquid without odor, and having a 

 saline and feebly caustic taste. It absorbs carbon dioxide from the air, 

 so that a pellicle of calcium carbonate forms on the surface of the liquid. 

 Reaction strongly alkaline.

ACTION OF LIME AND SOLUTION OF LIME. 



External. — Lime is caustic, but less so than potassium 

 or sodium hydrate. It is an irritant. The dust of quicklime 

 will cause conjunctivitis. If inhaled, it will cause iuflamma- 

 tion of the air passages ; if swallowed, irritation of the diges- 

 tive tract. The hydrate is a caustic also, but is not so active 

 as lime. Solution of lime is a sedative and astringent. 



Internal. — Neither lime nor slaked lime (calcium hydrate) 

 are used internally, except in the official preparations. 

 Solution of lime acts as a sedative, antacid, and astringent 

 in the stomach. It dissolves mucous secretions. Lime 

 water is also a mild astringent in the bowels. 



Uses. — Lime is employed outside of the body to destroy 

 putrefying organic matter by combining with water and 

 forming slaked lime, which absorbs many of the products 

 of decomposition. Whitewash, a mixture of slaked lime 

 and water, is not a disinfectant, although it covers sources 

 of infection. It may be made so by combination with
