WebHardy-Schulze rule. The transition from stable dispersion to aggregation usually occurs over a fairly small range of electrolyte concentration. This makes it possible to determine aggregation concentrations, often referred to as critical coagulation concentrations (CCC). The Schulze-Hardy rule summarizes the general tendency of the CCC to vary ... WebMar 28, 2016 · The inverse Schulze-Hardy rule was recently proposed based on experimental observations. This rule describes an interesting situation of the aggregation of charged colloidal particles in the presence of the multivalent coions. Specifically, it can be shown that the critical coagulation concentration is inversely proportional to the coion …
WebApr 7, 2024 · The Schulze-Hardy rules are a set of empirical rules used to predict the stability of colloids. According to these rules, the stability of a colloid is dependent on the ratio of the charge on the particles to their size.
