ResourceOn This Day – Jul 07 : Rocket apparatus fueled with solid 'explosive material'
The first of these rockets was successfully launched on 16th March 1926 by the American scientist and his colleagues in Auburn, Massachusetts. It was fuelled by liquid oxygen (O2) and gasoline, and reached a height of 12.5 metres.

ResourceColumn chromatography
The separation of mixtures produced in chemical reactions is often carried out by passing the mixture through a stationary phase of silica held in a column. Solvents move compounds at different rates through the silica allowing them to be separated into fractions by collecting the emerging solvent. This can ...
-
ResourceHeating under reflux
The term ‘reflux’ describes an arrangement in which a reaction is carried out in a boiling solvent with the vapour being condensed and returned to the reaction vessel. Refluxing is carried out when reactions need to be heated to give a reasonable yield of product in a reasonable time. ...
-
ResourceDean-Stark apparatus
There are many equilibrium reactions that yield water as a co-product. It is the co-produced water that prevents a high yield of product being obtained. The removal of the water is necessary to drive the reaction to completion and this is done using Dean-Stark apparatus. The reaction is carried out ...

DemonstrationSodium ethanoate ‘stalagmite’
Quickly grow your own ‘stalagmite’ from a supersaturated solution of sodium ethanoate in this demonstration. Includes kit list and safety instructions.
-
ResourceSteam distillation
The extraction of a crude mixture containing water-insoluble material (such as natural products) can be achieved by co-distillation with steam. Video: Steam distillation video
-
ResourceMelting point determination
The measurement of melting points is a relatively straightforward procedure that is carried out to determine the purity of a compound or to assist with its identification. A pure compound will melt over a relatively narrow temperature range, impurities both lower and widen the temperature range over which a compound ...
