in color (murexide, Eriachrone Dlack T, Pyrocatechol

Substances of the last mentioned group must be re-

the resonance system of the indicator. The ranE;e
of color change of MI, on formation. of a comilex
with the cathion is within the limits of its acid-
base changes. The functional maechanism of MI
ensues fron its coiq)lex-forminC characteristics and
its properties as an acid-base Indicator. In the
presence of the cathion with which the MI forms a
cor.Tplex, there takes rlace, within the pP_' mnGe of
the complex occurence, a disturbance of the acid-
base color chanGe of the MI; it is desirable that
this disturbance be associated with sharp color
changes within the pH range that is advanta6eous
for the deterudnation of the given cathion. Thie
function of MI depends upon its color system, acid-
base proy-erties, the complex-forraing group, and

MI II and III can be utilized for coq~_Iexoretric

for the masking of Hg ~'l In an acidic medium I forms
with HgBia white rapidly darkening precipitat-e which dis-
solves in an excess of I to form a colorless solution in
which Hg is combined wilh I as a very stable complex.
In an alkaline solution this gomplex is decomposecl with
separation of HgS. Agl- Cu; '~' and Fe also react with

of some metals by precipitation with cupral or by selective
extraction of diethyl-dithiocarbaminates with a suitable -
organic solvent. In such a case the cathions being deter-
mined are displaced from their compounds with cupral by
the action of HgCl and are transferred into the aqueous
phase in which they are determined by the described pro-
cedure after Hg'9"t has been masked by an addition of I.

ABSTIUCT: Xylenol orange is a very sensitive metallochro e indic
ator. It forms red or reddish-violet comr1exes with Bi Bi
'is precipitated quantitatively by sodfum diethyldithioc7-rbamate
(cupral) as a yellow precipitate soluble in organic solvents.
It is replaced from the complex salt by Ag. This is used for
an argentometric, determination of AgI and AgBr. An excess of
Ag will displace Bi in the cupral complex, and the free Bi will
form a distinctive eolor with the present xylenol orange, The
accuracy of this met1u)d is 0-3% for Iodides, 0,1% for chlorides,

PURPOSE: This book is intended for chemists and analysts.in research inistitutes
and plant laboratories.
COVERAM The book discusses the theory and practice of the application of
complexons in analytical chemistry, and deals in detail with the theory of
complexons,, the structare of forming complexes,, as well as methods for deter-
mining the stability constants of these complexes. The author describes in
_Q~l

Complexons In Chemical Analysis
SOV/4784
detail applications of complexons in gravimetric and volumetric analysis,
colorimetry, polarography, chromatography and ionophoresis, and in qua)-ita-
tive analysis. He also discusses complexometric titration (chelatometry)
methods, giving a detailed treatment of the theory of complexons and numerous
examples, of the practical applications of complexometry in the various
branches of chemical analysis compiled from the available literature up to
1955. The majority of the methods described in this book are the results of
studies made by the author and his coworkers at the Institute of Analytical
Chemistry of Charles University, Praguepublished from 1946 to 1952 in
Chemick6 Jisty. The editor of the Russian edftionp Yu. Y*.,. Lurlye, states
that the second Russian edition of the Czech work has been so enlarged in
comparison with the original edition as to constitute a new monograph.
Chapters I and II were written by Doctor 1. Kbryta, Doctor K. Macek wrote
the chapter on chromatography., Doctor V. Suk and Doctor M. Malat wrote the
section on complexometry in pharmaceutical analysis, and Doctor I. K8ssler
aided in composing the chapters on theoretical problems. The author thanks

the best predecessor for such corn planting should be
annual grain-legume mixtures (vetch-oat mixture), and the
best method of presowinG soil cultivation for after-crop
corn planting should be disking the stubble by a diqk har-

The focal tuberculin test was carried out in 59 subjects, who were divided into 4
groups- 13 non-tuberculous patients (rheumatism, congenital or pyogenic affections
etc.). 22 subjects suspected of tb, 13 patients suffering from stabilized tb and' I I
patients with progressive tb. The technique used was the following: 3 injections
were made: the first intradermal reaction with tuberculin in a concentration of
1: 1,000, the second with a non-specific protein (o.5- I mi. or milk) and the third
with tuberculin in a concentration of 1: 1,000 (1 mi.). Results: in the first group
the focal test was constantly negative: the second group presented .1 positive re-
action in 19 cases-. the third group in 7 cases and the patients of the fourth group

all presented a Positive focal reaction. The harmfulness formerly attributed to this
reaction is denied. Patients suffering from active 1b, who alone are susceptible to
accidents (only I case in the authors' statistics). should be handled with caution.
There were L4% of non-conclusive reactions. With this margin of error of 14%, the
