If the potential to the right of a species is more positive than the one on the left, then the its oxidation Eh-pH diagrams for geochemistry : D.G. Brookins. Springer-Verlag, New York, 1988, $89.50. (ISBN 0-387-18485-6).

The use of Eh-pH diagrams in geochemistry is widespread, and their application to many aspects of mineral paragenesis well documented. These diagrams have been proven useful for metallurgical purposes, for predicting species in solutions, for alteration products of ores and in hydrothermal systems, and many others. Arsenic Geochemistry in Groundwater System 31 Studying the Mahomet aquifer, Illinois, U.S.A., Holms et al 2004 [30], constructed Eh-pH diagrams for arsenic speciation.

E - pH diagrams are also known as Pourbaix Diagrams, after the author of the famous Pourbaix diagram handbook1. The simplest type of these diagrams is based on a chemical system consisting of one element and a water solution, for example, the Mn-H 2O system. The system can contain several types of species, such as dissolved ions, condensed oxides, hydroxides, oxides, etc. The E - pH diagram Figure 1.1 Eh-pH diagram of aqueous arsenic species in the system AsвЂ“O 2вЂ“H 2O at 25ВєC and 1 bar total pressure PENDING Figure 1.2 Arsenic speciation (arsenite and arsenate) against pH 1.2.2 Abundance and distribution Concentrations of arsenic in fresh water vary by more than four orders of magnitude (Table 1.1) depending on the source of arsenic, the amount available and the local

Eh and pH as environmental parameters in the electrochemical equilibrium diagram. Eh-pH diagrams showing reactions and products at electrochemical equilibrium are often referred to as Pourbaix diagrams. The oxide Bi 2 O 3 occupies much of the Eh-pH field above the sulfide- sulfate boundary, and is replaced by Bi 6 O 6 6+ at pH between 5.5 and 6 for activities of вЂ¦
