Abstract
IF a chemical reaction takes place with change of colour, colorimetric measurements at time intervals form a convenient method for examining the kinetics of the reaction. It is possible to improve the older methods1 based on this principle by the use of the Pulfrich-Stufenphotometer by Zeiss. This instrument permits of measurements: (1) at constant temperature; (2) for a large range of concentrations; (3) with monochromatic light; (4) in coloured and very volatile solvents.
