Explain about Electrophoresis (or) Cataphoresis (or) How would you detect the presence of charges on sol particles? (or) Explain about the method used to detect the presence of charge on sol particles. |
Answer» Solution : Electrophoresis (or) cataphoresis:  (II) If the sol particles MIGRATE to the cathode, then they possess POSITIVE charges and if the sol particles migrate to the anode, they have negative charges. Thus from the direction of migration of sol particles, we can determine the charge of the sol particles. Hence electrophoresis is used for the detection of PRESENCE of change on the sol particles.  |
