`As_2S_3` sol has a negative charge. Capacity to precipitate it is highest inA. `AlCl_(3)`B. `Na_(3)PO_(4)`C. `CaCl_(2)`D. `K_(2)SO_(4)` |
|
Answer» Correct Answer - A Negatively charged `As_(2)S_(3)` sol is coagulated most effectively by `AlCl_(3)`. This is because oppositely charged `Al^(+++)` ions have maximum charge. `Al^(3+) gt Ca^(2+) gt Na^(+)` |
