In electro-osmosis, the sol particles are prevented from migration whereas the dispersion medium migrates in the direction opposite to those of particles. Here, the medium is negatively charged.
During electro-osmosis of Fe(OH)_(3) sol a. Sol particles move towards anode b. Sol particles move towards cathode c. The dispersion medium move towards anode d. The sol particles do not move in either direction
