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)`
In a electrical field, the particles of a colloidal system move towards cathode. The coagulation of the same sol is studied using K_2SO_4(I) ,Na_3PO_4(II) ,(K_4[Fe(CN)_6] (III) and NaCI (IV). Their coagualating power should be :
Ca_(3)(PO_(4))_(2) +H_(2)SO_(4) to
Na_(2)CO_(3)+PbSO_(4) to PbCO_(3) darr+Na_(2)SO_(4)
Na_(3)PO_(4)+Fe_(2)(SO_(4))_(3) to FePO_(4) darr+Na_(2)SO_(4)
