The Learn Chemistry Wiki has been shut down
Thanks for visiting. In order to consolidate and improve our education resources, we've shut down the Learn Chemistry Wiki, and this page is no longer available.
For spectra and spectroscopy information, see SpectraSchool, Learn Chemistry’s spectroscopy hub.
For detailed safety information, visit CLEAPSS (England, Wales and Northern Ireland) or SSERC (Scotland), advisory services providing health and safety advice and documentation for science in schools. Non-UK schools may wish to consult local authorities.
