Vedclass · Answer

(B) The process of settling of colloidal particles is called coagulation or precipitation of the sol.When a positively charged colloidal solution is mixed with a negatively charged colloidal solution,they neutralize each other's charges,leading to mutual coagulation.According to the Hardy-Schulze rule,the coagulating power of an ion is directly proportional to its valence (charge). For a negatively charged colloidal solution,the coagulating power of cations increases with their charge.Therefore,the order of coagulating power is $Al^{3+} > Ba^{2+} > Na^{+}$.

Mixing of positively charged colloidal solution with negatively charged colloidal solution brings $ . . . . . . $. The decreasing order of coagulating power of $Na^{+}$,$Ba^{2+}$ and $Al^{3+}$ for negatively charged colloidal solution is $ . . . . . . $?
