For coagulation of 10ml of a positive sol, the volumes of IM each NaCl, Na_(2),SO_(4),Na_(3)PO_(4) and Na_(4)[Fe(CN)_(6)] required separately are P, Q, R and S ml respectively. Arrange P, Q, R and S in the descending order. |

Answer» Solution :For coagulation of a POSITIVE sol, negative IONS are required. As PER Hardy-Schulze rule greater the valence of the flocculating ions, greater is the flocculating power and lesser volume is required. Thus the correct order of the volume of solutions is ` P GT Q gt R gt S` . |
