Curent Project

Analytical Chemistry Division (V)


Number: 2005-014-1-500

Title: IUPAC Stability Constants Database - completion of data collection up to 2006

Task Group
K.J. Powell

Members: Tamas Gajda, Erich Königsberger, LanChi Königsberger, and Igor Sukhno

Remarks: continuation of project 2000-004-2-500

1. To bring the literature coverage in the IUPAC Stability Constants Database up-to-date to 2006, to be accomplished by 2008 (3.5 years). Coverage is currently complete to the end of 2002 for 26 mainstream journals, to 2001 for 11 journals, 2000 for 9 journals.

2. To establish a team of experts to supervise data entry and oversee quality control (all currently done at one university) and establish a succession of experts to continue this work beyond the current project.

Data compilation for SC-Database involves literature search, evaluation, data entry using the program SCEnter, and quality control checks on entered data. The data are then sent to the data coordinator, Academic Software (AS), for conflation of master files.

Data compilation was a voluntary effort (Commission V.6) until the mid-90's but this was unable to keep pace with publications. In 2000 a Division V project was funded by the Project Committee to "Complete data collection up to 2000+" (project 2000-004-2-500). This project, completed in April 2005,- captured data for 47 journals, ca 1995-2001,- captured some 1000 "missed" references (1970-95),- corrected many errors transferred from the book volumes (1900-1973)- completed compilation for 8 additional or new journals (environmental, engineering and biochemical) bringing the total to 55 journals.

SC-Database is used as the principal source of literature data for the steady stream of "Critical evaluations of stability constants" that are published by Division V. For this reason also, it is necessary to keep the database up-to-date. Although such evaluations come within the scope of Division V and its Solubility and Solution Equilibrium Data sub-committee, the relevance of the database is much wider, particularly to aspects of inorganic chemistry, physical chemistry and environmental chemistry. Division V is investigating ways of encouraging a more inter-Divisional ownership of the database.


This project was presented at a poster session at the IUPAC Congress/GA July 2005
