tantalum 2.10-6 _ 5-10-5 m; potassium iodide 2.10-4 - 2,10-5m;
hydrogen peroxide 2.10-4 _ 2.10-3 m;
hydrochloric acid 0.1 - 0-5 m. To obtain an equation for the
reaction velocity, the dependence of the latter on the
concentration of the individual reagents was investigated.

ABSTRACT: Values of the entropy of gaseous ions are often needed
for calculating the entropy of hydration of Ions for the
quantitative calculation of a series of cycles in which
gaseous ions appear in intermediate stages. The calculation
of the entropy of gaseous monatomic particles is carried
out using a well-known equation of statistical thermody-
namics (1) (Ref 2) in which the entropy of the rotation of
the monatomic Cases is neglected. In chemical equilibrium
at medium and high temperatures the entropy of the nuclear
spin can also be neglected (Ref 2). Thus in the calculation
of the entropy of a monatomic ion at standard conditions
only the atomic weight of the particle and the statiatical
weight of the electronic ground level must be kno-.,n. A

ABSTRACT; If a metal ion with an incomplete electron shell comes into a
field of anions or polarized molecules, the energetic main level
is split up into sublevels. The number of the latter can be com-
puted by the aid of the group theory (Ref 1) (Stark's intramole-
cular effect). If the sublevels in the gaseous ion below the
main levels are filled with electrons, additional energy is ob-
tained, the so-called extra-stabiliiation energy. The value of
it can be computed by a formula (Refs-2,3) E - FV, (1) where
V denotes the difference between two energetic levels and p is
a multiplier which is dependent on the electronic structure of
the metal ion and on the spatial arrangement of the field-form-
ing anions or molecules around the metal ion, For the dissolu-
tion of a salt in water the author gives equation (2). The field
formed in the crystal by the anions X is succeeded by the field
Card 1/3 formed by the H 20-molecules. In this case, the effect of th

crystal field constitutes a difference of the energies of extra-
stabilization (3)- A transformation of equation leads to:
AE - AFVH20 + FxAv (4), where AF - fH20- fXj AV VH20 - YX
holds. There is the possibility of indicating the entire course
of the value AE at least in a first approximation. Table I shows
the results of such computations for various ratios of VH20 and
VX. The values given in.table 1 show that the solution heats of
the salts in the sequencet Mn2+, Fe2+1 C02+' N12+9 CU2+, and Zn2+
do not change linearly with the change of the ordinal number.
In the case of copper salts, deviations in the direction of en-
dothermal effects (negative values of AE) do always occur. Sign
and magnitude of deviation in other salts depend on the field
force (Vx); in the case of weak fieldsp deviations occur in the
direction of exothermal effects# in the case of strong ones in
the direction of andothermal effects. Table 2 shows values of
solution heats taken from a reference book (Ref 5) for halides,
hydroxides, sulfates~ and sulfides of the mentioned metals as
Card 2/3 well as the deviations frozi such values dete~,iined by means of

linear interpolation. For reasons of conveni6nee, the sign of
deviation is-ohanged into the inverse. The course of obange in
halides reminds one of the first, type of change of AE(VH 20 OX),
that of hydroxides of the 2nd or 3rd type of change of
AE (V0 VH 0), and in the case of sulfides, the 4th type
2
(V ) V 0). The solubility of a salt is characterized by the
X H

amount of the solubility product (8.-P.). Logarithm of S.-Fe
(at constant temperature) is proportional to the change of free
energy-with an inverse sign AZ - - 2-3RT Ig S.-P. (5) ..
Table 3 supplies S--P- logarithms of hydroxides, oxyquinolates,
and sulfides of the.mentioned metals as well as the deviations
from the linear course. These data are in good agreement with
those given in tables 1 and 2. Thus, the above results confirm
the above mentioned theoretically derived rule. There are
3 tables and 7 references,-3 of which are Soviet.

A Plan to Introduce a Study of Advanced Methods of Chemical
Analysis
PERIODICAL: Vestnik vysshey shkoly, 1960, No. 3, PP- 77 - 79
TEXT: The question of organizing instructions on advanced methods of
chemical analysis, usually combined as physicochemical methods, came up
quite often in publications of institutions of higher educationt at the
konferentsiya po metodike prepodavaniya analiticheekoy khimii (conference
on Methods of Instructing Analytical Chemistry) held by the Ministerstvo
vysshego obrazovaniya (Ministry of Higher Education) in 1949 and was the
main point of discussion at the soveshchaniye po metodam prepodavaniya
analiticheskoy khimii (conference on Methods of Instructing Analytical
Chemistry) in 1957. For future technologists, the new curriculum provIdes
68 hours of instruction in methods of physicochemical analysis in the
fourth term. This will make it possible to add instruction in analytical

chemistry in the near future to all institutions of higher education
teaching chemical technology, including the large group of optical
methods (absorption and emission spectroscopy, nephelometry, turbidimetry,~
etc.), electrochemical methods (electroanalysis, polarography, potenti-
ometry, conductometry, etc.), and also radiochemical and other methods
of analysis. I. P. Alimarin, Corresponding Member AS USSR, tried these
methods of instruction with success at the Moskovskiy institut tonkoy
khimicheskoy tekhnologie (Moscow Institute of Fine Chemical Technology).
So far not even a name has been found for this new subjectl the author
suggests the name "Opticalg Electrochemical, and Radiochemical Analytical
Methods". The institute mentioned under "Association" started teaching
this subject in the schoolyear of 1957/58 to eight groups of about 200
students. The division of each course and the equipment of the labora-
tories are described, and the leneth of these courses is given as 20 - 30
hours and that of laboratory work as 40 hours.-The basic and auxiliary
sciences which form part of the above-mentioned subject are enumerated.

Finally, 13 problems for laboratory work are mentioned. A shortcoming
of these instructions is seen in the shortage of suitable literature,
since there is only one book that deals with this subject: "Fiziko-
khimicheskiye metody analizall (Thysicochemical Methods of Analysis") by
Yu. S. Lyalikov, published by Metallurgizdat, Moscow, 1951-'.A coworker of
the author translated and enlarged the English book by G. V. Yuing(Hewin
"Instrumental Methods of Chemical Analysis" ("Instrumentalinyye metody
khimicheskogo analiza"), New York, 1954- It would be desirable to increase
the courses to 30 - 35 hours and laboratory work to 60 - 70 hours.
Ivanovskiy sovnarkhoz (Ivanovo sovnarkhoz) is mentioned.

so far they have not been specially discussed at a conference. For
this reason the Ministerstvo vysshego i srednego spetaiallnogo

Training USSR) and the Commission for Analytical Chemistry of the
Akademiya nauk SSSR (Academy of Sciences USSR) held a Conference on
Kinetic Analysis Methods at the Ivanovskiy khimiko-tekhnologicheakiy
