Vedclass · Answer

(D) According to the Hardy-Schulze rule,the coagulating power of an ion is directly proportional to the magnitude of the charge on the ion of opposite sign to that of the colloidal particle.For a negatively charged sol,the coagulating power depends on the positive charge of the added cation.The given cations are $Ba^{2+}$ and $Al^{3+}$.Since the charge on $Al^{3+}$ $(+3)$ is greater than the charge on $Ba^{2+}$ $(+2)$,$Al^{3+}$ has greater coagulating power.

Which of the following ions has greater coagulating power for a negatively charged sol?
