Abstract
Lead and its more common salts have for a long time been used to perform a number of experiments. In recent years, owing to the importance of minimizing the production of hazardous chemicals, there is a tendency to replace experiments involving toxic compounds by others that, while illustrating the same principles, make use of products more environmentally friendly. Although in many instances this replacement can be made without significant loss of educational value, we consider it necessary to acquaint students with techniques used in the processing of hazardous chemicals. This set of basic experiments emphasizes that toxic products can be conveniently studied by using a combination of microscale techniques and simple schemes to recycle wastes. Here we propose a basic cycle for lead involving the consecutive transformation of lead(II) acetate to lead(II) formate, lead powder, and lead(II) oxide, with special emphasis on minimizing the production of wastes.
