Electrophoresis leading to coagulation of sols:
Coagulation is known as a process of aggregation or accumulation of colloidal particles to settle down forming a precipitate. When two oppositely charged sols are mixed, coagulation takes place due to neutralization.
During the process of electrophoresis, the colloidal particles are forced to move towards the oppositely charged particles, then they are discharged and collected at the bottom.
Thus, if the process lasts a long time, these ions are discharged and coagulated.
Example: Hemoglobin, can start to coagulate if the electrophoresis process will continue for a long time.
Hence, in the above-mentioned way prolonged electrophoresis leads to coagulation of sols.
