Describes three laboratory practice courses offered for chemical technician certification at the South Australian Institute of Technology. (MLH)

Describes the construction and operation of a moveable videotape studio that is used in a chemistry laboratory to illustrate laboratory skills and experiments. (MLH)

Presents short articles on: recycling disposable plastics for laboratory use; an inexpensive source of atomic and molecular models; a simplified Boyle's Law demonstration; and a lab demonstrating energy transformation. (MLH)

Presents questions and answers about the effect of metabolism on substances in the human body. (MLH)

Describes an experiment that illustrates the role of hydrogen bond formation in producing a heat of reaction when ethanol and water are mixed. (MLH)

Describes a scheme that uses precipitation, gas evolution, complex ion formation, and flame tests to analyze for the following ions: Hg(I), Hg(II), Sb(III), Cr(III), Pb(II), Sr(II), Cu(II), Cd(II), As(III), chloride, nitrate, and sulfate. (MLH)

Describes a laboratory procedure for identifying carbon-14 labelled acetic acid by first converting it to acetophenone, then oxidizing the labelled carboxyl with permanganate. (MLH)

Describes a method for determining the rate constants of enzyme reactions involving two substrates with the use of double reciprocal plots. (MLH)

Describes a procedure for performing an enzyme assay colorimetrically on tyrosinase obtained from fruits and vegetables. (MLH)
