Q. 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

Surface Chemistry

Solution:

According to this law the coagulating effect of an ion on dispersed phase of opposite charge increases with the valency of the ion. The precipitating power of $Al^{3+} , Ba^{++}, Na^{+}$ ions is in order $Al^{3+} > Ba^{2+} > Na^{+}$.
