Gives a detailed description of the constructon of equipment needed for redox equilibria experiments and the measurement of the electromotive force of voltaic cells. This information is provided to solve the problem of inadequate, expensive equipment required for A-level chemistry practical work. (JN)

Provides a detailed description for the construction of equipment needed to investigate acid/base equilibria through the measurement of pH and potentiometric titrations. Suggested experiments and calibration techniques are explained. This information helps to solve the problems of inadequate, expensive equipment required for A-level chemistry…

"Science, Technology and Society" was identified an essential strand in the new Science Education curriculum guide. Shortly after the severe acute respiratory syndrome (SARS) threat to Hong Kong technical dealers introduced Infrared non-contact thermometers as a solution for schools to measure body temperature for a large number of…
