TEXT: The polarographic method was used to study pH of Cr (011)3 formation in
Cr2(SO4)3, solutions with 3.8 - 10-3 MLCr-concentration.in the preserice of 0.1 1.1
Na,SO4 0.2 M (NIQIS04 and a series of buffer admixtures. The authors revealed
the effect of.thesZ admixtures upon the reduction of Cr3+ on the lig-electrode.
They showed the increase in pH of Cr(OH) deposition in the presence of (NHU)2~04,
urea,'and remicarbazide, as compared.tG12S04 solution. Stable- complex Cr-i+ VOM-
pounds are formed with citric and tartaric acids; such compounds dc. not form Or-
hydroxides at any pH values of the solution and are not reduced on the Hg-Olec-
trode a-c pH > 2-5 - 3.5. There are 24 references.

~TEXT: The effect of current density and some other factors on the
oxidation of Cr III - Cr VI was studied. A 100 yield in Cr VI was
shown to be possible only at very low current densities (30 - loo a/m
The current yield of Cr V1 is reduced considerably by an increas4~~in
current density, irrespectively of the ratio Cr III : Cr VI. An addition:
of Fe III which is hardly effective, reduces the current yield of Cr VI
slightly, and shifts the anode otential toward negative values. The
p
dependence of the current yield on the current density and onthe:degree
of Cr III oxidation was analyzed by plotting partial polarization curves
-for the oxidation-of Cr III and.oxygen formation. One of the causes of-
-this dependence lies in the low values of maximum current density'
