It 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 125 theoretical and 50 practical problems were set in the IChO in the mentioned twenty years. In the elaboration of this collection the editor had to face certain difficulties because the aim was not only to 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 corrections in order to unify the form of the problems. However, they did not concern the contents and language of the problems. Many of the first problems were published separately in various national journals, in different languages and they were hard to obtain. Some of them had to be translated into English. Most of the xerox copies of the problems could not be used directly and many texts, schemes and pictures had to be re-written and created again. The changes concern in particular solutions of the problems set in the first years of the IChO competition that were often available in a brief form and necessary extent only, just for the needs of members of the International Jury. Some practical problems, in which experimental results and relatively simply calculations are required, have not been accompanied with their solutions. Recalculations of the solutions were made in some special cases ony when the numeric results in the srcinal solutions showed to be obviously not correct. Although the numbers of significant figures in the results of several solutions do not obey the criteria generally accepted, they were left without change. In this publication SI quantities and units are used and a more modern method of chemical calculations is introduced. Only some exceptions have been made when, in an effort to preserve the srcinal text, the quantities and units have been used that are not SI. Unfortunately, the authors of the particular competition problems are not known and due to the procedure of the creation of the IChO competition problems, it is impossible to assign any author's name to a particular problem. Nevertheless, responsibility for the scientific content and language of the problems lies exclusively with the organizers of the particular International Chemistry Olympiads.
