Abstract

The flocculating and stabilizing action of sodium fluoresceinate
on silver iodide sol was investigated by tyndallometric, fluorimetric
and electrophoretic measurements. The limits of the precipitation
region were determined. The amount of sodium fluoresceinate
adsorbed on AgI-particles was calculated from fluorimetric
measurement data. The fact that the end-point of fluorimetric
titration of the system AgN03-KI-sodium fluoresceinate
takes place at pH 5 is in complete agreement with the results of
tyndallometric and electrophoretic observations of ours and other
author's experiments.
