Hardy-Schulz rule. [ ′härd·ē ′shu̇lts ‚rül] (physical chemistry) An increase in the charge of ions results in a large increase in their flocculating power.

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).

2013-08-20 · Hardy-Schultz Rule The coagulation of a colloidal solution by an electrolyte does not take place until the added electrolyte has certain minimum concentration in the solution. 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). A simple and inexpensive experiment for verifying the Schulze-Hardy rule. 2017-02-21 · The Schulze-Hardy rule suggests a strong dependence of the critical coagulation concentration (CCC) on the ionic valence.

Y1 - 2009/9/1 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.

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 values of CFC. In this work it is reported a correct determination of CFC for di- and tri-valent ions using different types of silica nanoparticles.

The schulze hardy rule is an empirical realization of these property. 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.
