The image shows an open textbook with a diagram of a chemistry experiment illustrating the laboratory preparation of nitrogen from air. The experiment involves passing air through caustic soda solution to remove carbon dioxide, then through heated copper turnings to remove oxygen, and finally collecting the nitrogen gas over water. The text on the left discusses the properties and preparation of nitrogen. The right side of the page contains a table listing names of nitrogen compounds.
