WebApr 8, 2024 · The Hardy Scruz rule states that greater the valency of flocculating ions, greater will be the coagulating power of that ion. It means that the flocculation value of an electrolyte is measured from the valency or charge. higher the charge on the ion, higher will be the coagulation value. WebAt high values of surface potentials, γ ≈ 1 and equation 5.21 predicts that the coagulation concentration should be inversely proportional to the sixth power of the valency Z. Thus coagulation concentrations of those electrolytes whose counter-ions have charge numbers 1, 2, 3 should be in the ratio 100:1.6:0.13.
