Answer:
The colloidal sol of Fe(OH)3 has positive charge due to the preferential adsorption of ferric ions (Fe3+) on the surface of the ferric hydroxide particles.
Fe(OH)3+Fe3+→Fe(OH)3⋅Fe3+
Hence, during electrophoresis of colloidal sol of Fe(OH)3, the colloidal particles move towards cathode (negatively charged electrode).
