FERRI PHOSPHAS — FERRIC PHOSPHATE 



Synonyms. Ferri Phosphas Solubilis U. S. P. VIII, Soluble 

 Ferric Phosphate 



Ferric phosphate, U. S. P. is ferric phosphate rendered soluble 

 by the presence of sodium citrate. It belongs to the scale prepara- 

 tions of iron, see p. 410. 



LIQUOR FERRI SUBSULPHATIS — SOLUTION OF FERRIC 

 SUBSULPHATE 



Synonym. Monsel's Solution 



This is an aqueous solution of variable composition containing 

 an amount of basic ferric sulphate corresponding to not less than 

 13.57 per cent, of metallic iron. The residue left upon evapora- 

 tion of this solution to dryness is called " Monsel's Powder." 



Therapeutics. Monsel's solution and povi^der are strong stypt- 

 ics. They are less irritant than the solution of the chloride but 

 form a hard black scab which is objectionable. The scab may 

 cover deeper hemorrhages if the solution is poured into a wound 

 and for this reason it is better to apply the solution or powder 

 upon cotton or gauze. With the better methods of controlling 

 hemorrhage at hand, these preparations are rarely used. Solu- 

 tion of the subsulphate diluted with a little water may be of serv- 

 ice to check bleeding from the stomach or intestines but, like other 

 local hemostatics, is worthless for other forms of internal hemor- 

 rhage. 



LIQUOR FERRI TERSULPHATIS — SOLUTION OF FERRIC 



SULPHATE 



This is an aqueous solution which should contain about 36 per 

 cent, of normal ferric sulphate, corresponding to not less than 10 

 per cent, of metallic iron. It occurs as a reddish brown liquid, al- 

 most odorless, having an acid, strongly styptic taste, and an acid 

 reaction. It is used in the preparation of the antidote for arsenic.
