ABSTRACT:
An indicator for the documentation of chlorine by discoloration of potassium iodide applied on a support is to be improved so that it is sufficiently sensitive for the documentation of the low chlorine concentrations and also has, for the documentation of high concentrations, a stable dicoloration. To this end it is provided that the indicator comprises an addition of manganese chloride.
