Abstract
A number of surface-active substances have been added to solutions of chloride, and the latter has been titrated with silver nitrate solution in the presence of an adsorption indicator. Although the use of agar was found to offer some advantages, that of hydroxypropylmethylcellulose gave rise to end-points that were much superior. The same additive also greatly facilitated the determinations of bromide and iodide. Attempts to determine these halides in admixture were, however, unsuccessful.Keywords
