Liquor Acidi Arsenosi 



This is an aqueous solution which should contain not less 

 than 0.975 per cent, nor more than 1.025 per cent, of arsenous acid, 

 corresponding to approximately 1 per cent. 



Arsenic Trioxide 0.5 Gm. 



Diluted Hydrochloric Acid 2.5 Gm. 



Distilled Water, a sufficient quantity 



to make 50. Gms. 



Mix the diluted hydrochloric acid with 12.5 grams of distilled 

 water in a tared (weighed) flask, add the arsenic trioxide, and boil 

 the mixture until the arsenic trioxide is completely dissolved. Then 

 allow it to cool, add enough distilled water to make the product 

 weigh 50.0 grams, and filter. 



Remarks. A clear, colorless liquid, v odorless, having an acidu- 

 lous taste and acid reaction. This preparation is employed in those 

 prescriptions in which Fowler's solution would be incompatible. 



Liquor Calcis. Lime Water 



This is a saturated aqueoiis solution, which should contain not 

 less than 0.14% of Pure Calcium Hydroxide. (Ca(0H)2. 



The percentage of Calcium Hydroxide varies with the tempera- 

 ture at which the solution is prepared, and diminishes as the tern-
