Titration, conductometric differential

Well-established examples of binudear cobalt(III) complexes with carbonate bridges are very limited. Kremer and Mac-Coil confirmed the existence of the p-carbonato-bis(pentaamminecobalt(III)) complex, [(NH3)s Co(C03) Co(NH3)s] (originally prepared by Kranig by potentiometric titration, conductometric charge determi-, nation, visible, ultraviolet, and infrared spectra, behavior against ion exchange resin, counter-ion substitution, thermogravimetric analysis and differential thermal analysis.

The quantitative analysis procedure involves gravimetric detn of the HMX on a moisture-free basis after benzene extraction of, and differential detn of TNT. Moisture content is detd by conductometric titration of sample in an acetic-sulfuric acid suspension. Acetone insoluble matter is determined gravimetrically... 

Conductometric titrations offer several advantages compared with potentiometric titration methods, such as better precision and better differentiation of the basic components in polymers, but they are more laborious. ASTM D 4928-96 is an established KF method for the determination of water in crude oils. 

The latexes were cleaned by ion exchange and serum replacement, and the number and type of surface groups were determined by conductometric titration. The molecular weight distributions of the polymers were determined by gel permeation chromatography. The stability of the latexes to added electrolyte was determined by spectrophotometry. The compositional distribution was determined by dynamic mechanical spectroscopy (Rheovibron) and differential scanning calorimetry, and the sequence distribution by C13 nuclear magnetic resonance. 

Differential conductometric titration has been used [674, 675] for the determination of chlorine in some chloroorganosilane mixtures. The method is based on the quantitative conversion of the chlorosilanes into the alkylthiocyanato derivatives by the action of ammonium thiocyanate, followed by conductometric titration in methyl cyanide/ethyl ether (2/3) solvent with 0.1 N amidopyrine in benzene. The monosub-...
