188 POTASH, ACETATE, CITRATE, AND TARTRATE 



with oxygen and loses its purple or pink colour, is a test of 

 the amount of organic contamination in water, other fluids, 

 or even in air. Its expense, however, precludes its general 

 use in veterinary practice. 



DOSES, etc. Potassium permanganate has been given to 

 horses and cattle as an alterative and febrifuge in drachm 

 doses ; but observation does not justify its preference to the 

 nitrate or chlorate. For antiseptic and deodorant purposes 

 one part permanganate is dissolved in 50 to 1000 parts of 

 water. A 1 to 1200 solution is used for intra vaginal 

 and intrauterine injection after difficult parturition, and in 

 cases of retention of the foetal membranes. 



POTASSIUM ACETATE. Potassii Acetas. Acetate of Potash. 



POTASSIUM CITRATE. Potassii Citras. Citrate of Potash. 



Potassium acetate is prepared by fusing the product of the 

 interaction of acetic acid and potassium carbonate. It occurs 

 in white, foliaceous, satiny masses, or in granular particles, 

 very deliquescent, and freely soluble in water and alcohol. 

 In their actions and uses the acetate and citrate closely 

 resemble the nitrate. Without action on the gastric juice, 

 they render the urine and other secretions strongly alkaline. 

 Like other alkaline salts containing a vegetable acid, when 

 they enter the body they are mainly converted into the 

 carbonate, and are eliminated in the urine, producing 

 diuresis. The acetate and citrate of potassium are the in- 

 organic diuretics most frequently prescribed in human 

 medicine. Doses for horses and cattle, 3J V - to gj. ; sheep

ACID POTASSIUM TARTRATE. Potassii Tartras Acidus. 

 Cream of Tartar. KHC 4 H 4 6 . 



POTASSIUM TARTRATE. Potassii Tartras. K 2 C 4 H 4 6 .H 2 0. 



The crude tartar or argol, obtained from the interior of 

 wine-casks, when purified by solution and crystallisation, 

 occurs in white, hard, crystalline masses, with a sharp acid 

 taste. When administered it takes up water with avidity,
