Conductometric titration of hydrochloric acid in gastric juice.
We describe a procedure for the determination of hydrochloric acid concentration in gastric juice by means of a conductometric titration of the 50-fold diluted sample with an aqueous ammonia solution. The conductometric method of endpoint indication leads to a definite location of the equivalence point in the titration of hydrochloric acid. The proposed method is simple and accurate and shows a...
متن کاملMicrocomputer Automation of the Conductometric Titration of Hop Alpha-Acids
A general-purpose microcomputer was used to au tomate the determination of lead conductance value by titration. The microcumputer, presented with an extracted sample in a beaker, controls the addition of titrant and the taking of data, performs all calculations, and finally prints the corrected result along with a record of the titration. A number of operating parameters were studied in order t...
متن کاملIonic liquids with metal chelate anions.
A series of stable (air, water stable and with good thermal stability) and hydrophobic ionic liquids based upon metal chelate anions were synthesized, which were shown to be effective, mild, and easy to recycle catalysts at the same time stable solvents for the oxidation of cyclohexene.

H 9 : Mg : Cl = 0,152 : 0,575 : 1,080, d.h. es lag ein Gemisch von 0,152 Mol ,HMgCl‘ mit 0,423 Mol MgCl2 (beide solvatisiert mit THF) vor. Bei der Bestimmung des aktiven Wasserstoffs wurde eine mit fl. N2 gekühlte, mit Kieselgel gefüllte Falle vorgeschaltet um eventuell bei der Hydrolyse freigesetztes Äthan (C2H5MgCl = HCl —> C2H6 + MgCl2) vom gebildeten Wasserstoff ab zutrennen. In keinem Ver...
متن کاملObtaining higher transesterification rates with subtilisin Carlsberg in nonaqueous media.
Three phase partitioning (protein precipitate obtained as an interfacial layer between lower aqueous and upper t-butanol phases, formed by the addition of ammonium sulphate and t-butanol to the aqueous solution of protein) followed by lyophilization in the presence of two-component excipient resulted in 400-480x increases in transesterification activity of lyophilized powders of subtilisin Carl...
