Question

How prolonged electrophoresis leads to coagulation of sols?

Answer 1

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.
