Abstract

In this article, in order to develop the technology of teaching chemistry, several different methods of obtaining calcium and its compounds in laboratory conditions are considered. Information on the use of chicken eggshells, which are a natural and cheap raw material, but considered as waste, for the production of calcium element compounds, and at the same time, the possibility of introducing waste-free technology.
