when chlorinated lime, a mixture of calcium chloride and 

 hypochlorite, results. 2 Ca 0,H, + 2 CI, = Ca CIA, Ca 

 Clj + 2 HjO. It may also be regarded as a mixture of lime 

 and chlorine. 2 Ca 0,H, + 2 CI, = 2 Ca 0, 2 CI, + 2 H,0. 



Properties. — A white, or grayish-wliite granular powder, 

 exhaling the odor of hypochlorous acid, having a repulsive 

 saline taste, and becoming moist and gradually decompos- 

 ing on exposure to air. In water or in alcohol it is only par- 

 tially soluble. It evolves chlorine on exposure to the air or 

 on addition of an acid. Chlorinated lime possesses an 

 alkaline reaction and bleaching properties. 



Dose. — Only of value externally. 



PREPARATION. 



Liquor Calais Chlorinatce. Solution of Chlorinated Lime. (B. P.) 

 This solution should yield about 3 per cent, of chlorine. 



Liquor Sod^ Chloeinat^. Solution of Chlorinated Soda. 

 (U. S. & B. P.) 



Synonym. — Liquor sodse chlorinatse, Labarraque'a 

 solution, E. An aqueous solution of several chlorine com- 

 pounds of sodium, containing at least 2.6 per cent., by 

 weight, of available chlorine. 



Derivation. — A solution of sodium carbonate, 150; chlo- 

 rinated lime, 75 ; in water to make 1,000. 



Properties. — A clear, pale, greenish liquid, having a 

 faint odor of chlorine and a disagreeably alkaline taste. 



Dose. — Only of value externally. 



ACTION AND USES OF CHLOEINE. 



Chlorine gas, in the presence of organic matter and 

 moisture, unites with the hydrogen of water and sets free 

 nascent oxygen. When chlorine comes in contact with sul- 

 phuretted hydrogen, it removes and destroys the compound. 

 Chlorine is thus a powerful oxidizing disinfectant agent 

 and deodorizer. One-quarter of 1 per cent, of chlorine in 

 solution is an effective germicide. When chlorine gas is
