| contents | Electrometric investigations on the formation of cerium(iii) tungstates as a function of ph Shiva Prasad André Luiz de Brito Fiquene Ana Cristina Muniz Silva Valderí Leite Duarte Química Tungstates cerium(III) electrometry The course of reaction between cerium(III) nitrate anddifferent sodium tungstates (Na2WO4, Na10W12O41 and Na6W12O39) hasbeen followed by means of pH and conductometric titrations betweenthe reactants at different pH levels, in aqueous and alcoholic media,with each of the reagents alternatively used as titrant. The electrometricexperiments provide definite evidence of the formation of normal-Ce2O3.3WO3 and para- 5Ce2O3.36WO3 tungstates of cerium in thevicinity of pH 6.2 and 5.3. The formation of normal tungstate is almostquantitative and the pH titrations offer a simple means for determinationof cerium(III) or tungstate solutions at suitable concentrations and pHrange. 2000 artículo científico 0100-4670 https://www.redalyc.org/articulo.oa?id=42902507 en http://www.redalyc.org/revista.oa?id=429 Eclética Química application/pdf Universidade Estadual Paulista Júlio de Mesquita Filho Eclética Química (Brasil) Num.1 Vol.25 |
