| Abstract: | Experimental data on the equilibria Fe2+/Fe3+ and SO32−/SO42− in the system Fe(OH)3(H2SO4)-Na2SO3-H2O are presented. The quantitative relations between the reduction of Fe(III) and the precipitation of FeSO3·2.5H2O as a Fe2O3 precursor have considered graphically.__________Translated from Zhurnal Prikladnoi Khimii, Vol. 78, No. 1, 2005, pp. 41–44.Original Russian Text Copyright © 2005 by Vasekha, Motov. |
