TITLE: Some special features of the operation of the positive

PERIODICAL: "Vestnik Elektro"omyshle-nn sti" (Journal of the

(USSR)'.
ABSTRAM.Galvanic cells based on the electro-chemical system
n ta C 0
'/-2 r2 7. ~2SO4/zn are still used be-cause of their
comparatively high power, 'their ability to work at low
temperatures and the possibility they afford of compact
constructiom:. During the discharge of a chromic acid cell
some phenomena are observed, the nature of which are not
yet clear. For instance, under some conditions 6f-dis-
charge the cell voltage drops in jumps of 0~.'27- 0'.3 volts
after wh 'ich the element continues to operate at normal
capacity. Under other conditions of discharge the cell
voltage suddenly falls almost to zero despite the presence
of a considerable reserve of unused active substances.
Card Both these phenomena are associated with step-wise
change
1/5 in the potential of the carbon electrode. The effect of

electrode in a chromic-acid cell. (Cont'.) 110-7-10/30
step-wise change in the -potential of the carbon electrode
by 0.1-0".3 volts in the negative direction has been called
the "partial passivation" of the carbon, and the effect
of step-wise reduction of potential by one volt or more
is called "total pasdivation!' of the carbon. It is well
known that cathodic polarisation of metals in chromic
acid occurring at some definite current density causes a
sharp potential jump in the negative direction after which
separation of hydrogen commences. A similar potential
jump has also been observed on the carbon electrodes This
effect which is apparently analogous with."total passiva-
tion!' of the carbon is usually explained as being due to
the formation on the cathode of a screening diaphragm of
trivalent compounds.
Carbon materials may differ widely in physical-chemical
properties and it was therefore of interest to find out
whether partial passivation is a general property of
carbon electrodes or is associated with special features
of some particular types of carbon'. The investigations
Card were made on 9 types of carbon of different physical-
2/5 chemical propertiesq see Table 1~. The investigations
were
Some special features of the operation of the positive
electrode in a chromic-acid celf. (Cont..) IID-7-10/30
made by taking polarisation curves, and a number of
pbysical-chemical properties of the carbon were also de-
termined.
Fig.1 shows curves of the relationship between the poten-
tial (measured against a noimal hydrogen-electro~le) and
the current densityv. and Fig.2 shows curves of the poten-
tial as a function of time for different types of carbon,
it is seen that for all-types of carbon, at current
densities of 180-200 mA/cm4 there is a sharp ump of poten-
tial of'1 to f.'2 V in the negative direction itotal passi7-
vation). Separation of hydrogen commences after the jump'.
At lower current densities of 5-60 mA/cm2 three of the nine
types of carbon investigated displayed step-wise potential
displacement'of 0'.1-0'.3 V (partial passivation)'. The same
three types of carbon display step-wise potential reduct-
ion during polarisation at a constant current density of
5-40 MA/oM2.
Fig'.3 shows polarisation curves taken on a rotating carbon
Card electrode at different speeds of rotation'. As the speed
3/5 is increased from 0 to 1200 rpm the current density at
which
Some special features of the operation of the,~ositive
electrode in a chromic-acid cell'. (Cont'.) 1 -7-10/30
total passivation commences increases threefold'.
In order to studv the influence of the solution composi-
tiony potential/time curves were determined with constant
current density on the cathode in solutions with different
concentrations of chromic and s-alphuric acids, trivalent
chromium and salt. Fig'.4 shows curves taken on solutions
with different concentrations of chromic acid with con-
stant total solution acidity'. On the basis of the.experi-
mental data that was obtained it may be concluded that the
effect of total passivation. of carbon is caused by definite
concentration changes in the layer of solution adjacent to
the electrode. The removal of these concentration changes
also removes total passivation of the carbon which demon-
strates the absence of an insoluble diaphragm of chromium

ABSTRACT: In the case of cathodic polarization of a carbon - or
any other in-
ert electrode - in a solution of chromic acid a sudden check of
the
reaction 9f reduction of the chromic acid anion Cr207 +14 R+ +
+ 6e -4 2cr+++ + 7H20 is often observed. This check is
accompanied
by a instantaneous shift of the potential to the negative,which
is
followed by a reaction of hydrogen separation (a complete
inacti-
vation of the electrode). Apart from this phenomenon, in some
in-
stances a small shift of a few tenths of a Volt have been
observed
in the case of densities, where the potential of hydrogen
separa-
tion has not been reached. The complete inactivation of inert
elec-
trodes in solutions of chromic acid was the object of investiga-
tions of several authors. In the paper under consideration the
in-
fluence of a series of factors (composition of the solution, of
stirring and of the treatment of the electrode) on the partial
in-
activation of the carbon electrode was studied. From the figures
it can be seen, that the potential of the upper and lower niveau

condition of the electrode, as well as the duration of the
active
state are dependent on the composition of the solution. The in-
fluence of identical components of the solution on the
potentiil
of the active state and on that of the partially inactivated
elec-
trode is differing. In particular the effect of an addition of
an
indifferent salt to a highly concentrated solution is falling
in-
to the eyes. The salt instantaneously shifts the potential of
the
partially inactivated electrode to the negative, whereas the
poten-'
tial of the active electrode is very little affected. An
introduc-
tion of three-valent chromium, even in1high concentration has
practically no influence on the partial inactivation. An
addition
of chromiumsulfate in high concentrations, however, shifts the
po-
tentiil of a partially inactivated electrode. This is
apparently
not connected with the presence of three-valent chromium. A
simi-
lar shift also takes place in highly concentrated solutions of
sul-
phuric acid and chromium acid. These effects detailed here are
to
be considered as a check of the electrochemicil reaction and
not
as a change in their nature. The experimantal results obtained
here
contradict the conception, that the check is produced by the
for-
mation of a diaphragm consisting of compounds with small
solubility

activation is connected with a modification of the state of the
oxyde layers on the surface of the electrode. Several facts
in favour of the concept, that some forms of the surface oxydes
correspond to the active condition of the electrode. They
vanish
during the cathodic polarisation and reappear during the soft
ano-
die polarization of the carbon. The phenomenon of partial
inact-i-
vation of the carbon-electrode can be explained as a
modificati':~.,
of the electrochemical mechamism of the reaction of
ion-reduction
of the 6-valent chromium into three valent chromium. This
transi-
tion takes place because of the modification of the oxyde
layers
on the electrode sueface. Phenomena of the same qualitative
cha-
racter were observed on inert platimum and gold electrodes.

of the alkaline solution according to the equation
Zn + HgO - ZnO + Hg (1). If, hovever, zinc hydroxide is
formed (2), the emf of the chain is bound to decrease with
the increasing alkali concentration since the water activity
falls. Principal attention in these experiments was paid
to the maximum approximation to the state of equilibrium.
In preliminary experiments it was found that the omf of iner-
curic-oxide elements is fully stabilizad 2-3 months after
the preparation, and remains practically unchanged during
the subsequent 9 months and more. A partial additional charge
with an elimination of 10-15% capacity of the element great-
ly accelerates the stabilizing process of the emf. Heret the
solution is particularly saturated with zincatew and the
solid phase falls out. Figure 1 shows the dependence, found
in this way, of the emf on the alkali concentration in the
KOH-solutions saturated with potassium zincate betpeen 0.6
and 12-5 n. It shows that the emf is constant between 0.6 and
1.5 n, and amounts to about 1-344 volts. This value

TITLE: Anodic Passivation of Zinc in Alkaline Solutions

PERIODICAL; Doklady Akademii nauk SSSR, 1960p Vol- 132, No. 3,
pp. 639-642
TEXT; It was the aim of this paper to investigate the influence
exerted
by the adsorption of oxygen and by the formation of an oxide film
upon
the passivation of zinc. The anodic behavior of Zn was investigated
in
KOH by means of osoilloscopic; recording of the potential - time
curve
y(t) at constant current density i on a rotating disk electrode.
"Pass
=itn was determined (Qpass is the amount of electricity necessary
for
passivation, t n is the time up to pa8sivation). Fig. 1 shows the
diagrar~
1/qpass - f(i). At mean current densities there is a linear
dependence
between 1/Qpass and i. In the case of i being low, Qpass becomes
dependent
on the rate of stirring, and in the case of a very low i and a high
rate
Card 1/3

of stirring, no passivation occurs. From these results as well
as from
the anodic polarization curve (Fig. 2), the curve of the
increase of the
potential after 60-min passivation and after switching off the
anode
current (Fig. 3) as well as from the dependence of the
dissolution rate
of the passivated electrode on the speed of rotation (Fig-
4)-the authors
draw the following conclusions: The dissolution of zinc
depends on the
dissolution rate of the zinc oxide (and peroxide). As
passivation occurs
already at potentials (-1.1 to -1.0 v), which are more
negative than the
reduction potential of the zinc peroxide in the oxide film,
passivation is
primarily based on a change in the concentration of KOH and
the zincate
retarding dissolution in the liquid layer near the electrode.
The forma-
tion of the oxide film is a secondary process. There are 4
figures and 7
