PERIODICAL: Magyar Ke'miai Poly~irat, no. 1, 1963-, 4-17*

sity s and the concentration c of aqueous strong electrolytes'where
the ions do not form complexes:

the solubility. T~e'nu'merical-values(X, 2, and r are tabulated -for
aq. HC1, 11Br and HI, alkali'halides, NaOH and KOH, at 0, 25 and
500C. Deviations of densities calculated acqording to Eq. (1) from
actual values are listed.. The physical, meaning of a, 0, and 4- is
discussed. It is assumed that in a dilute solution of a monovalent
electrolyte water molecules*'assume a definite configuration around
every ion,-extending over 10 - 12 water molecules: This-configu-
ration is different from that in pure water.and depends only on
temperature'. If the concentration of the solution is so high that
there are less than 10 - 12 water-molecules surrounding each ion,
their configuration will be identical t9 that of the primary shell
of hydration. The.following model is assumed to describe the space
requirements of the components of a concentrated monovalent elec-
trolyte solution. The voldme of'an ionic.crystal is resolved into
those of the two ions. The space requirempnts-of each type of ion-
are considered. The'same method is applicible'to aqueoub solutions
.in which.the water molecules,are coribidered as.spheres of 1.38.~

TOPIC TAGS: radioisotope, iodine, xenon
AB.STRAC,r: The radioactive iodine tgq_tope~ 1-125 was prepared in a nuc-
lear reactor for the first time in Hungary by employing the following
process: Xe-124(n,y)Xe-125 4 1-125. The 99.9% pure xenon gas was sealed!
in a glass capsule during irradiation. The neutron flux during the ope-1
ration was 1.1 x 1012 n cm.,2 sec.'I. The product had an activity of
258 4C and was entirely carrier-free. Experiments are in progress to
assess the potential therapeutical applications of the isotope..' The
authors thank the Reactor En ris for taking upon themselves the
extra problems of-tfie--Ka"6-1r-Aar ~railoin and preparptions as well as for
numerous recomme dations. Orig. art. has: 3 figures, 3formulas, and
