1.	Which of the following electrolytes is least effective incoagulating firrec hydroxide solution?
Answer» KBr `K_(2)SO_(4)` `K_(2)CrO_(4)` `K_(4)[Fe(CN)_(6)]` Solution :Smaller the charge on ANION, lesser will be its COAGULATING power. `therefore` KBr have `Br^(-)` with least charge of -1 on br THUS KBr is least effective in coagulating `Fe(OH)_(3)`.
