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

Redox titrations are the titrimetric method developed to know the
concentration of the analyte by creating redox reaction among titrant and analyte. The
basic principle involved in the redox titration is the oxidation-reduction reaction, in
which electron transfer from one reactant to another reactant takes place. Oxidation
means loss of electron and reduction means gain of electron. These must happen at the
same time, when a substance loses electrons, there must be some other substance to
accept those electrons. The main applications associated with redox titrations are
determining the reduction potential of sHdrA flavin from Hyphomicrobium
denitrificans, water in non-aqueous solutions, dissolved oxygen in water and
determination of alcohol content in the whiskey bottles, etc.
