प्रश्न
What are the applications of Electrophoresis?
उत्तर
Applications of electrophoresis:
- On the basis of the direction of movement of the colloidal particles under the influence of the electric field, it is possible to know the sign of the charge on the particles.
- It is also used to measure the rate of migration of sol particles.
- A mixture of colloidal particles can be separated by electrophoresis since different colloidal particles in the mixture migrate at different rates.
