electrode and the stabilized value of the potential of th(- anti-

the potential value of the freshly deposited,8ctive antir;iony jur-
face. As may be seen (Fig 2) the beginning of the oxidation of
antimony is not connected with the absolute value of the uolarlza_
tion quantity of the electrode. If, as could be observed in the
experiments, the displacement of the equilibrium potential in the
positive direction depends on the surface oxidation, oxidat-Jor. in
more acid solution would be bound to take place more slowly and
consequently also the displacement of the equilibrium potential
would be smaller. Figure 4 reveals the polarization curves in a
more acid solution. Polarization curves in the case of electic-
deposition of antimony from hydrochloric acid solutions viere com-
pletely different (Fig 5). It can be seen from it that the rate

ABSTRACT: The authors studied the deposition of silver from solutions
of 2n AgNO 3 and 2n KNO 3P and 4n AgNO 3+ 2n IC-10 3' The number
of crystaln which had formed on the ourfacc of the electrodes
was determined under the microocope. This number increases
with the volta,(I-e; this direct relationship is represented
in diagrams (Figs 1,2, and 3). Silver and Platinum electrodes
were used. The preceding anodic polarization yi(21ded many
more crystals at the cathode than did the polarization of
the cathode with direct current. This phenomenon did not
occur at the insoluble platinum electrode. Probably the
number of crystals increases by virtue of the fact that the
number of active centers on the surface of the electrode
Card 1/2 increases, since sharp points^--nd tiny crystals tend to be

Three Anomalies of the Electric Precipitation of Chromium
(Tri anomalii pri clektroona--hdonii .hroma)
PERIODICAL: Izirestiya kkademii nauk SSSR. utdeleniye khimicheskikh nauk,
1959, Nr 7, pp 1207-1210 (USSR)
ABSTRACT: In this paper the three anomalies arising on the electric
reduction of chromic acid in the presence of sulphuric acid are
demonstrated. They are the following: a) The reduction of the
hexavalent chromium to the trivalent state runs very quickly at
a low potential and is very sharply suppressed at hiCh potentials.
b) Stirring of the electrolytes decreases the cathode polarization
sharply at low potentials and has no influence on that at high
potentials . c) On increasing the electrode potential within a
certain potential range the polarizing current decreases. The
dependence of the current density on the cathode poli-irization at
direct currentj in the presence of H 2s04 and without it, on
stirring and without stirring is rapresentecl in fiazzes 1, 2, 3.
It is supposed that the anomalies being noticed on the electric
Card 1/? precipitation are combined with the appearance of a film on the

surface of the electrode. Since the film occurs only in the
presence of H2 so4 this is indicative of the fact that the
sulphuric acid influences the formation of a film positively in
the range of the chromium precipitation potential and that it
does not destroy the film as is generally supposed. There are
3 figures and 4 referenceo, 3 of which are Soviet.

TITLE: An Investigation of the Rate of Conjugated Electrochemical
Reactions
PERIODICAL: Doklatr Akademii nauk SSSR, 1959, Vol 128, Nr 4,
PP 773-776 (USSR)
ABSTRACT: In several papers (Refs 2,3) it was proved that a mutual
influence of the ions occurs in the joint reduction of metal
ions. In the joint reduction of the ions of Cc and Ni, Fe and
Co, or Fe and Ni, for instance, that ion is discharged more
quickly which in the case of a more negative potential is
separated alone. This process is complicated by the simul-
taneous discharge of hydrogen ions. The authors indicate
their data for the precipitation of Fe, Ni, H 2 (Table 1,
Fig 1) and Fe, Co, H 2 (Fig 2). In both cases, the separation
of Fe is accelerated while that of Ni and Co, respectively,
is inhibited. The following possible influences are discussed:
(1) Alteration of the state of the cathode surface, (2) altera-
tion of the structure of the Helmholtz layer, (3) alteration
Card 1/3 of the concentration and state of ions in the electrolyte.

An Investigation of the Rate of Conjugated BOV/20-128-4-38/65
Electrochemical Reactions
Neither the influence of (3) (e.g. alteration of ion hydra-
tion), nor that of (2) (alteration of ion concentration in
the Helmholtz layer (A. N. Frumkin, Ref 5)) can clarify the
phenomena observed. Yu. S. Petrova proved that the adsorp-
tion rate of hydrogen and hydroxides is different for the
individual metals of the Fe-group. Ni adsorbs more H, Fe more
hydroxide. If the layer adjacent to the electrode is alkalized,
the Ni-separation is inhibited due to the adsorption of
hydroxides on the Ni-surface. V. ff. Kuznetsova ascertained
that the reduction of Fe increases with a decreasing simul-
taneous separation of H 2' A Ni-Fe alloy adsorbs less H2 and
delivers more Ni-hydroxides than Fe-hydroxides since the
latter are only formed in a more acid medium. This explains
the observed inhibition of the Ni-reduction, and acceleration
of the Fe-reduction in the conjugated process. Thus, the
state of the cathode surface, and the concentration of the
components in its vicinity, are the cause of the phenomena
described. There are 2 figures, 1 table, and 6 Soviet ref-
Card 2/3 erences.

pp. 1255-1259
TEXT: The action of the rate of passivation on the electrochdmical
reduction of metal ions in aqueous solutions was examined. A series of
experiments took place in manganosulfate solutio-na with and without
additions of ammonium sulfate at pH - 8 and fl at 250C. The results show
(Table) that the reduction of the manganese ions takes place through an
activation of the electroda surface by ammonium sulfate. In a further
series of tests a common electrolytic depositing of molybdenum and ni~',
from ammonPm citrate solutiona was examined. The rate of depositinLf, (,-
the nicke12'rises through the activation of the surface with increasirj
concentrations of ammonia. One of the main obstacles to the reductior of
metal ions is the passivation of the surface. Metals with a great

passivation tendency are hard to reduce on the cathode, anc, can 'ue
divided into three groups in this respect: 1) Metals which are deposit.9,
by relatively low overvoltage, such as Sn, Cd, Cu, Ag, etc., 2) Metals
which are deposited at high overvoltage, such as Fe, Ni, Co, and Cr,
Mn, etc., 3) Metals which cannot be deposited in pure form from aqueous
electrolytes, such as Mo, IN, U, Nb, Ti, Ta. In order to reduce metal
ions, it is necessary to produce conditions which hinder passiYation
of the electrode surface, or at least strongly reduce it. R. I. Agladze

TITLE: Joint Discharge of Metal Ions in Real Conjugate Systems
PERIODICALs Doklady Akademii nauk SSSR, 1960, Vol. 135, No. 6,
PP. 1413 - 1416
TEXT: It is the purpose of the present investigation to prove that the
joint discharge of metal ions of different kinds does not take an additive
course but is a conjugate system. Therefore, not the overvoltage of the
individual metal ions with respect to the electrode, but their overvoltage
with respect to the alloy must be taken into account. From the fraction of
polarization of each of the ions entering the electric double layer, from
its capacity and its ability of penetrating into the double layer, the
following relation is obtained: 0 + (RT/nP)ln(a C IE a C alloy

into the electric double layer, -~1 , -22 the overvoltage in deposi-
tion on the alloy. In such conjugate systems it is possible, owing to the
different effects of the electrodes upon the overvoltage of the various
ions, that both the reduction rate of the more positive metal ions and
that of the more negative ions changes. This was proved by the joint
discharge of nickel and iron ions. The discharge rate of Ni ions was lower
in a joint discharge with Fe, although its reduction potential is more
positive in the absence of Fe. The effect of temperature upon the dis-
charge rate is represented in Fig.3. The discharge rate of nickel ions
increases with a0rise of temperature,while that of iron ions decreases,
so that above 90 C the electrodeposited alloy contains more nickel than
iron. A. N. Frumkin and A. I. Krasovskiy are mentioned. There are

author investigates the theory on the Joint discharge of metal ions in ideal
non-conjugated and natural conjugated systems. In the latter case, the effect
of various factors on the rate of the electrochemical process is analyzed. Con-
ditions of joint discharge in natural conjugated systems are discussed. On the
basis of experimental data submitted by a number of scientists, changes in tile
rate of ion discharge in joint reduction are analyzed. The following factors are
discussed: depolarizing and passivating effects of the backing; the effect of
surface-active substances and surface films and the effect of the composition o.f

Title Biological activity of alpha-aminopbosphinic acids
Periodical : Dok. AN SSSR 98/5, 849-852, Oct 11, 1954
Abstract : The biological activity of alpha-aminosphosphinic acids (toxic when in
large concentrations), is discussed. The biological activity of these a
acids is best expressed in the inhibition of birus multiplication in
the mosaic disease of tobacco. The effect of these acids and glycol
on the titer of influenza virus in growing chicken embryos was investi-
gated and the results are described. Eleven references: 7-USSR; 2-USA;

-Y,&-- VOP.VIRUS. 1957~'3 (179-181) Tables 2
The purpose of the present studies was to establish a reciprocal interaction of
Ehrlich carcinoma cells and various viruses. To 2 ml. of aseptically taken ascites
fluid were added 2 ml. of virus suspension at the dilution of 10-1 to 10-7 and after
mixing the specimen was allowed to stand for one hour at 0* or room temperature.
To test the viability of cancer cells mice were administered i.p. the mixture of
ascites fluid and viruses. Control animals received ascites fluid diluted with physio_
logical saline solution in 1:2 ratio, kept for I hour at the same temperati,re as in
the case of experimental mice. In order to determine the virus virulence mice were
given the virus-ascites mixture intracerebral, intranasal or intraplantar. The
following viruses were used: herpes simplex (strain L), fixed rabies (Moscow
strain), tick-borne encephalitis (strain JaM-3) encephalomyelitis (strain SW).
encephalomyocarditis (strain MM), influenza A (strain PR-8), extromelia (strain
Gajdamowicz) and fowl plague (strain Ukraina). Results: after intracerebral ad-
ministration of either ascites fluid or ascites-virus mixture it was found that the
highest mortality rate was due first to the mixture, next to the transplantation of
the neoplasm and finally to the administration of viruses. Therefore, neither
oncolytic action of viruses nor any Interaction of cancer cells and viruses could be
established. Whereas 8016 of mice succumbed 12 days after i.p. inoculation of the
neoplasm, those inoculated with the neoplasm and virus mixture showed a mortality
rate amounting to 50-97% depending on the species of virus used. Similar results
were obtained with intranasal or intraplantar inoculation of the experimental ma-
terial. The above results regarded by the author as preliminary, are not consistent
with those of other investigators who have established an oncolytic action of viruses.

Original
Periodical: Chem. listy, 1956, Vol 50, No 1, 11-22
Abstracts The effect, of water vapor on the,debydrogenation of ethylbenzene (I)
to styrene has been investigated. A zinc oxide catalyst or porcelain
chips were used, and the flow of I was varied; reaction temperatures
of 500-7000 and different H20tI ratios were used. It is sho,,m that
in the presence of H20 vapor, the catalytic dehydrogenation of I is
slowed down at temperatures below 6000 and accelerated at higher tem-
peraturest. Dealkylation and cracking are inhibited in the presence
of H20 vapor. It is indicated that because of side reactions, the
equilibrium constant for the dehydrogenation of I could not be es-
Card Vi tablished experimentally.

The constants in the Van Laar equations -sere
calculated for all the systems. The behavior
of the system ethylbenzene - styrene is prac-
tically ideal. The constant C for the tertiary
system has been calculated from the binary sys-
tem constants by applying the Vol Law: C = 0.5
(0.591 - 0.755 / 0.475 - 0.685) - 0.187. The
relative volatility values have been calculated
from the activity coefficient, and from the
former - the equilibrium compostion of the liq-
uid and vapor phases of the tertiary system. The
calculations have been verified by measurements.
