Precise Coulometric Titrations of Potassium Dichromate
This paper reports results of a continuing investigation to evaluate coulometric methods of analysis and to develop highly precise and accurate analytical methods for important materials, based upon this technique. Earlier papers described the coulometric titrations of acids and bases [1] 1 and of halides [2]. The present research is concerned with a typical oxidation-reduction titration, the a...
متن کاملSintering in Nitrogen Atmosphere of Iron-Rich Glass-Ceramics
The sintering and the crystallization of two iron-rich glass compositions (45–75m powder fractions) were studied in air and nitrogen atmospheres. The phase formation was evaluated by differential thermal analysis, while the densification, by dilatometry; the crystalline phases were identified by X-ray diffraction and the structure observed by scanning electron microscopy. It was highlighted tha...
متن کاملA Student-Designed Potentiometric Titration: Quantitative Determination of Iron(II) by Caro's Acid Titration
Oxidation–reduction titrations and potentiometric methods provide a convenient experimental means to quantitatively determine compositions of unknown mixtures containing oxidizable/reducible species. Over the past decade, numerous titration methods have appeared in this Journal (1–6) and in standard laboratory manuals (7–10) involving common titrants such as potassium dichromate, iodine, potass...
متن کاملInternational Comparisons for Coulometric Determinations of Dichromate Used to Develop Certified Reference Material for Oxidation-Reduction Titration
Inicialmente, para adquirir experiência na determinação coulométrica da pureza do dicromato, realizou-se uma comparação bilateral entre os institutos nacionais de metrologia (INM) do Brasil e da Rússia. Em seguida, objetivando comparar os resultados das medições do dicromato de potássio (K2Cr2O7) entre os INM que utilizam a coulometria com elevada precisão para certificar materiais de referênci...
متن کاملIsolation of chromium resistant Bacillus sp. MRKV and reduction of hexavalent chromium potassium dichromate
The ability of Bacillus sp. MRKV isolated from tannery effluent which shows resistant towards hexavalent chromium potassium dichromate (K2Cr2O7) was evaluated in this study. The bacterial strain was assayed for its reducing ability towards K2Cr2O7. The study revealed that the isolated strain has the ability to reduce the hexavalent chromium and the optimal conditions required for the chromium r...
