Abstract
A simple method for microdetermination of chlorine and
bromine is described. Halogens are absorbed by lead chromate at
about 400°, and determined from the :increase of weight of lead
chromate. It was found that at 4!00° microquantities of halogens
catalyse quantitatively the oxidation of sulphur dioxide to sulphur
trioxide; thus from the combined weight of the halogen and sulphur
trioxide the percentage of sulphur and halogen can be calculated.
