2017-02-21 · The Schulze-Hardy rule suggests a strong dependence of the critical coagulation concentration (CCC) on the ionic valence. This rule is addressed theoretically and confronted with recent experimental results. The commonly presented derivation of this rule assumes symmetric electrolytes and highly charged particles. Both assumptions are incorrect.

Derjaguin and Landau and Verwey and Overbeek worked independently and used the knowledge from Schulze-Hardy rule to describe the stability of lyophobic colloids to develop this theory (the classic DLVO theory) which explains the result of particle interaction in lyophobic colloids. Rediscovering the Schulze-Hardy Rule in Competitive Adsorption to an Air-Water Interface Patrick C. Stenger, Stephen G. Isbell, Debra St. Hillaire, and Joseph A. Zasadzinski* Department of Chemical Engineering, University of California, Santa Barbara, California 93106-5080 Received March 19, 2009. Revised Manuscript Received June 29, 2009 Abstract The applicability of the Schulze–Hardy rule to haematite and haematite/humate mixtures has been investigated by measuring the rate of fast and slow coagulation after the addition of increasing concentrations of mono, di and trivalent ions.
Sep 22, 2020 The results reported here show that the standard Schulze-Hardy-Rule (SHR), based only in the valence z, is not longer valid to obtain the right
On the other hand, the inverse Schulze-Hardy rule was only given as an empirical dependence based on experimental observa-tions. [9] Therefore, the aim of this paper is to present the derivation of the inverse Schulze-Hardy rule … This is known as the Schulze-Hardy rule. Derjaguin and Landau and Verwey and Overbeek worked independently and used the knowledge from Schulze-Hardy rule to describe the stability of lyophobic colloids to develop this theory (the classic DLVO theory) which explains the result of particle interaction in lyophobic colloids.
On the basis of Hardy-Schulze rule explain why the coagulating power of phosphate is higher than chloride.

Schulze hardy rule. According to hardy schulze rule greater the valency of the active ion or flocculating ion greater will be its coagulating power. In the coagulation of a negative colloidal solution the coagulating power is as. A simple and inexpensive experiment for verifying the schulze hardy rule.

The applicability of the Schulze–Hardy rule to haematite and haematite/humate mixtures has been investigated by measuring the rate of fast and slow coagulation after the addition of increasing concentrations of mono, di and trivalent ions. Haematite colloids follow the rule for mono, di and trivalent ions. According to Hardy-Schulze rule, greater the valency of the active ion or flocculating ion, greater will be its coagulating power.

The Schulze–Hardy rule is a well‐established observation in colloid science (can be derived from the DLVO theory) that demonstrates the relationship between the critical coagulation concentration (CCC) of colloids and the valence of extra counterionic electrolytes ( z ), with a simple mathematical relationship of CCC≈ z−6.
https://doi.org/10.1351/pac198052051151 2013-02-15 · The Schulze–Hardy (SH) rule is an empirical rule, stating that the coagulation concentration c cr of hydrophobic sols decreases very strongly with the valency z of the counterion. It stems from the end of the nineteenth century, and its qualitative validity has since been confirmed over and again for a variety of sols and conditions. Schulze hardy rule the generalization that the critical coagulation concentration for a typical lyophobic sol is extremely sensitive to the valence of the counter ions high valence gives a low. The coagulation capacity of different electrolytes is different. Request PDF | Schulze-Hardy rule revisited | The classical Schulze-Hardy rule suggests that the critical coagulation concentration (CCC) decreases as the inverse sixth power of the counterion 2020-december-23.

Shu lts här dē rül chemistry the sensitivity of lyophobic colloids to coagulating electrolytes is governed by the charge of the ion opposite that of the colloid and the sensitivity increases more rapidly than the charge of the ion. The applicability of the Schulze–Hardy rule to haematite and haematite/humate mixtures has been investigated by measuring the rate of fast and slow coagulation after the addition of increasing concentrations of mono, di and trivalent ions. Haematite colloids follow the rule for mono, di and trivalent ions. According to Hardy-Schulze rule, greater the valency of the active ion or flocculating ion, greater will be its coagulating power.

The destabilising power of an ion can be determined by measuring the critical coagulation concentration (CCC) of an electrolyte, i.e. the minimum concentration required to rapidly coagulate a given colloid. The Schulze-Hardy rule is an empirical realization of these property. I enclosed some images that illustrate some predictions for spherical gold nanoparticles. Unfortunately, I lost the reference where I found them and I am not able to find it again.
