WebThe Hardy Schulze Rule is a rule in chemistry used to determine the coagulating value of a solution and thus deals with the process of coagulation in a solution. It was discovered by … WebMay 18, 2024 · The classical Schulze-Hardy rule suggests that the critical coagulation concentration (CCC) decreases as the inverse sixth power of the counterion valence. While this dependence can be derived from the theory of Derjaguin, Landau, Verwey, and Overbeek (DLVO), this derivation relies on unrealistic assumptions.

A well dispersed colloidal suspension consists of individual, separated particles and is stabilized by repulsive inter-particle forces. When the repulsive forces weaken or become attractive through the addition of a coagulant, particles start to aggregate. Initially, particle doublets A2 will form from singlets A1 according to the scheme WebApr 4, 2024 · Complete step by step answer: > Hardy Schulze rule states that the amount of electrolyte required for the coagulation of a definite amount of a colloidal solution is …

It was discovered by William Hardy and Hans Schulze. Index Schulze Hardy Rule Statement What is Coagulation The Process of Coagulation Hardy Schulze Rule Example FAQs WebAnswer: Hardy-Schulze rule: The coagulation power of a precipitated ion is more if its valency is high. For example, the coagulation power series of Al 3+, Na + and Ba 2+ is Al 3+ > Ba 2+ > Na +. In a sentence this rule state as “Greater is the valency of the oppositely charged ion of the electrolyte being added, the faster is the coagulation”.
