The coagulation value in millimoles per litre of the electrolyes used for the coagulation of `As_(2)S_(3)` are given below: I. `(NaCl)=52` , II. `(BaCl_(2))=0.69` III. `(MgSO_(4))=0.22` The correct order of their coagulating power isA. `IgtIIgtIII`B. `IIgtIgtIII`C. `IIIgtIIgtI`D. `IIIgtIgtII` |
|
Answer» Correct Answer - C For electrolytes, according to hardy-schulze rule: Coagulating power `xx(1)/("Coagulation value")` Thus, the correct order is `{:(MgSO_(4),gt,BaCl_(2),gt,NaCl),((III),,(II),,(I)):}` |
