Abstract
The precipitation of silver chloride from homogeneous solution has been studied by conductance and light scattering measurements. The silver chloride was produced by the hydrolysis of allyl chloride in aqueous silver nitrate solutions such as to give a wide range of [Ag+]/[CI-] ratio at the onset of precipitation. Monodisperse sols exhibiting Higher Order Tyndall Spectra were formed at silver nitrote concentrotions furthest removed from the zero point of chorge which was found to be at pAg=396 by electrophoresis. In the region of the zero point of charge the sols showed maximum polydispersity in size and shape with marked twinning. The growth in the initial stages was found to be controlled by an interface process.
