Question

What happen when.a- When strong light beam is passed through a colloidal solution,b-An emf is applied across a colloidal solution.

Answer 1

Dear student ,

The beam of light is seen being reflected by the particles in a solution that is the scattering of light within the solution takes place.

If an electric field is applied to a colloidal sol, the dispersed phase particles are found to move towards the electrode of opposite charge. It is called elctrophoresis.
