ACIDI METER

ACI I >S 



Acidimeter (as-id-im'-et-er) [acidum, acid ; piirpov, a 

 measure]. An instrument for performing acidimetry. 



Acidimetry (as-id-im'-et-re) [acidum,&cvi; fierpov, a 

 measure]. Determination of the free acid in a solu- 

 tion bv an acidimeter, or by chemical reactions. 



Acidity [as-id f -it-e) [acidu?n f acid]. The quality of 

 being acid ; sourness ; excess of acid. 



Acidology (as-id-ol'-o-je) [antr, a bandage, a point; 

 /a) or, a treatise]. The science of surgical appliances. 



Acidometry ias-id-omf-et-re). S 'imetry. 



Acidopeirastic {as-id-o-pi-ras' -tik) [ii»f, a point; 

 Keipa&iv, to test]. See Akidopeirastic. 



Acidosteophyte (as-id-os'-te-o-fit) [cwac»a point ; o 

 phyte]. A sharp, or needle-shaped, osteophyte. 



Ac'ids, Aromatic. Acids derived by replacing hydro 

 gen in the benzenes by carboxyls. They are crystalline 

 solids that generally sublime undecomposed. Most of 



them dissolve with difficulty in water. A., Diazo. 

 See Diazo Acids. A., Dibasic, acids containing two 

 carboxyl groups. I bey are solids, crystallizable, and 



rally volatile without decomposition. Thej 

 mostly soluble in water and have a .-tronLj acid reaction. 

 See Table. A., Fatty, a class of monobasic acid-, 

 formed by the oxidation of the primary alcohols 

 more complex fatty a< id-, are found in all ojeagin 

 compounds, where they exist combined with glycerin, 

 forming fats. The fatty acids have a general formula 

 C n H 2n 02. See /(//'/,■. A., Monobasic, products of 

 the replacement by oxygen of the two hydrogen atoms 

 i to the carbon-carrying oil. These acids 

 enter into combination with a univalent basic radical 

 to fond a neutral salt, or a salt containing one equiva- 

 lent of a base. A., Organic, acids characterized by 

 the carboxyl group CO.OH.
