As per Hardy-Schulze formulation, the flocculation values of the following for ferric hydroxide sol are in the order : |
|
Answer» `AlCl_(3) gt K_(2)[Fe(CN)_(6)] gt K_(2)CrO_(4) gt KBr = KNO_(3)` The minimum CONCENTRATION of an electrolyte which is required to cause the coagulation or flocculation of a sol is known as flocculation VALUE. Flocculation value is inversely proportional to coagulation power (coagulation power is directly proportional to the valency of the ions causing coagulation). `Fe(OH)_(3)` sol is a positive sol and THUS we have to consider the valency of the anions in the given electrolytes. `K_(3)[Fe(CN)_(6)]ltK_(2)CrO_(4) lt KBr = KNO_(3) = AlCl_(3)` |
