For a positively charged sol , the flocculating power of KCl , MgCl_(2) , Cr Cl_(3) and SnCl_(4) will be in the order

Ferric hydroxide sol is more readily conagulated by Na_(3)PO_(4) in comparison to KCl. Why ?

each question constain STATEMENT-1(Assertion ) and STATEMENT - 2 (reason). examine the statement carefully and work the correct answer accoridng to the instructions given below : STATEMENT-1: For coagulation of positively charged sols, [Fe(CN)_(6)]^(4-) ion has higher coagulating power than that of PO_(4)^(3-),SO_(4)^(2-),Cl^(-) STATEMENT-2: The size of colloidal particle are larger than the size of true solution particles.

Al(NO_3) has higher coagulating power then MgSO_4 for Fe(OH)_3 sol.

Under the influemce of an electric field, the particles in a sol migrate towards cathode. The coagulation of the same sol is studied using NaCl,Na_(2)SO_(4) , and Na_(3)PO_(4) solutions. Their coagulation values will in the order a. NaClgtNa_(2)SO_(4)gtNa_(3)PO_(4) b. Na_(2)SO_(4)gtNa_(3)PO_(4)gtNaCl c. Na_(3)PO_(4)gtNa_(2)SO_(4)gtNaCl d. Na_(2)SO_(4)gtNaClgtNa_(3)PO_(4)
