PAST COMPETITION TASKS

THE COMPETITION TASKS
FROM THE PAST INTERNATIONAL CHEMISTRY OLYMPIADS,
organized in the years 1968 - 2008, are collected in the publication:

THE COMPETITION PROBLEMS FROM THE INTERNATIONAL CHEMISTRY OLYMPIADS
(Editor: Anton Sirota, Issued by IChO International Information Centre and IUVENTA, 1139 pp.)

It appeared in two volumes (Volume 1, 2008, 405 pp. and Volume 2, 2009, 734 pp).

The publication has been published by the IChO International Information Centre in Bratislava (Slovakia) on the occasion of the 40th anniversary of this international competition.

Not less than 279 theoretical and 96 practical problems are contained in this collection. In its elaboration the editor had to face certain difficulties because the aim was not only make use of past recordings but also to give them such a form that they may be used in practice and further chemical education. Consequently, it was necessary to make some correction in order to unify the form of the problems. However, they did not concern the contents and language of the problems.

Unfortunately, the authors of the particular competition problems are not known since due the procedure of the creation of the IChO competition problems, it is impossible to assign any author's name to a particular problem. Thus, responsibility for the scientific content and language of the problems lies exclusively with the organizers of the particular International Chemistry Olympiads.

More details you can find in the Prefaces to both volumes.

The collection ( VOLUME 1 and VOLUME 2 ) is available on this website. Furthermore, you can find particular documents each containing sets of tasks of five International Chemistry Olympiads.
