Rapid analysis of plating baths by a direct-reading thermometric method.
Methods are described for the rapid analysis of plating baths by measurement of the heat evolved in a reaction between the reagent and the component to be determined. The novel feature of the method is the use of reagents which have zero heat of mixing, so that the temperature scale can be directly calibrated in concentration units for a particular determination. A determination takes only 5 min and the precision is equal to that of the classical methods. Procedures are given for the analysis of nickel and chromium plating baths.
