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 valence. Here the derivation of the inverse Schulze The Schulze-Hardy rule (1) and the low charge DH limit (3) were both derived theoretically. 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 based シュルツ・ハーディの法則.

The minimum amount of an electrolyte ( millimoles ) that must be added to one litre of a colloidal solution so as to bring about complete coagulation or flocculation is called the Coagulation or Flocculation Value of the Such a strong effect on the CAC of colloidal systems is usually approximated by the Schulze-Hardy rule in terms of 1/Z 6 , where z is the valence of the cation (Lyklema 2013).

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.

According to Hardy-Schulze rule, greater the valency of the active ion or flocculating ion, greater will be its coagulating power. The coagulation capacity of different electrolytes is different.

Yeah Hardy-Schulze rule does say that for a positive sol as the charge of the anion in the salt increases the flocculating value decreases (if the charges of anions in 2 salts are different then does not depend on number of negative ions per molecule of salt and the rule still holds good).
