Abstract
SHS investigation development is considered from the geographical and historical viewpoint. 3 stages are described. Within Stage 1 the work was carried out in the Department of the Institute of Chemical Physics in Chernogolovka where the scientific discovery had been made. At Stage 2 the interest to SHS arose in different cities and towns of the former USSR. Within Stage 3 SHS entered the international scene. Now SHS processes and products are being studied in more than 50 countries.
Abstract
Complexometric titrations (also known as chelatometry) are used mainly to
determine metal ions by use of complex-forming reactions. It is a form of volumetric
analysis in which the formation of a colored complex is used to indicate the endpoint of
a titration. In this method, a simple ion is transformed into a complex ion and the
equivalence point is determined using metal indicators or electrometrically. An
indicator capable of producing an unambiguous color change is usually used to detect
the endpoint of the titration. The versatility, sensitivity, and general convenience of
complexometric titrations are dependent on the correct choice of indicators endpoint
detection.
