Question
A colloidal solution is subjactedto an electrical field. the particles move towaeds anodes. The coagulation of same sol is studied using NaCl, BaCl2 AlCl3 Solution. Their coagulat ing power should be
Options
A.NaCl > BaCl2 > AlCl3
B.BaCl2 > AlCl3 > NaCl
C.AlCl3 > BaCl2 > NaCl
D.BaCl2 > NaCl > AlCl3
Solution
The movement towerds anode shows that sol is nagtive. For coagulation of nagative
Cation with higher charge is more effective
Cation with higher charge is more effective
