Question

Hardy-Schulze rule explains the effect of electrolytes on the coagulation of colloidal solution. According to this rule, coagulation power of cations follow the order
(a) Ba⁺² > Na⁺ > Al⁺³
(b) Al⁺³ > Na⁺ > Ba⁺²
(c) Al⁺³ > Ba⁺² > Na⁺
(d) Ba⁺² > Al⁺³ > Na⁺

Answer 1

c option is the correct answer

Acc to Hardy shulze rule -- Greater the charge on coagulating ion , greater will be the coagulation power

Answer 2

Answer:
