Heating Group 1 metals in air and in chlorine

Description

This is a demonstration that shows the reactions of Group 1 metals in air and in chlorine.  It does not clearly show the trends in reactivity of Group 1 metals, which are better demonstrated by the reactions in water, which follow on well from this demonstration.

ADDITIONAL INFORMATION

This is a resource from the Practical Chemistry project, developed by the Nuffield Foundation and the Royal Society of Chemistry. This collection of over 200 practical activities demonstrates a wide range of chemical concepts and processes. Each activity contains comprehensive information for teachers and technicians, including full technical notes and step-by-step procedures. Practical Chemistry activities accompany Practical Physics and Practical Biology.

The experiment is also part of the Royal Society of Chemistry's Continuing Professional Development course: Chemistry for non-specialists
