    Flame tests (the wooden splint method)

    The method described in this experiment is intended for students to carry out and avoids the need for the use of concentrated hydrochloric acid. It also avoids the cost and contamination problems associated with the use of nichrome or platinum wires.

    On This Day - Mar 23 : First noble gas reaction

    Noble gases were thought to be completely inert, but English chemist Neil Bartlett observed that mixing platinum hexafluoride with xenon formed the yellow solid xenon hexafluoroplatinate. This led to many more discoveries of noble gas compounds.

    On This Day - Jan 18 : Edward Frankland was born

    Frankland introduced the theory of valence when he realised that atoms can only form a certain number of bonds to other atoms. He also co-discovered helium (He), pioneered organometallic chemistry, and was a leader in the field of water purification.
