Summary

Zeta-potential of copper ferrocyanide sol falls, and its hydrogen ion concentration increases continuously with the addition of chlorides of potassium, barium, and aluminium till the sol falls to coalescence. The effect of thorium nitrate on the above sol is quite distinct from the rest in the sense that with its addition zeta-potential first falls rapidly, attains a minima, and then it again rises. The lowering of zeta-potential as well as the increase in hydrogen ion concentration of this sol by the cations of different valencies follows the Hardy-Schulze rule.

Zusammenfassung

Das Zeta-Potential von Kupfer-Ferro-Cyanid-Sol sinkt, und seine Wasserstoffkonzentration steigt kontinuierlich mit Zufügung der Chloride von Kalium, Barium und Aluminium, bis das Sol ausfällt. Der Effekt von Thoriumnitrat ist völlig verschieden. Das Zeta-Potential fällt zuerst sehr stark, erreicht ein Minimum und steigt dann wieder. Die Erniedrigung des Zeta-Potentials wie auch der Anstieg der Wasserstoffionenkonzentration dieses Soles durch Kationen verschiedener Wertigkeit entspricht der Hardy-SchulzeRegel.
