Mechanistic studies are discussed and general experimental procedures are reported. In addition several interesting developments in the chemistry of this reagent are outlined, that is, heteroatom oxidation, cleavage reactions and also its use in sequential reaction processes.
In this context a unit on gold and gold mining might well be a sensible choice at Grade 10 or 11 levels in Papua New Guinea to extend the pupils' knowledge and understanding of the interactions between science, technology and society. Practical work based on the extraction of gold or the chemistry of gold is limited mainly due to its high cost.

1) Multiple choice questions: A) Rutherford, Geiger, and Marsden performed experiments in which a beam of helium nuclei (α particles) was directed at a thin piece of gold foil. They found that the gold foil: (a) severely deflected most of the particles of the beam directed at it (b) deflected very few of the particles of the beam and deflected these only very slightly (c) deflected most of ...
