Question

Define Tyndall effect. Differentiate between electrophoresis and electroosmosis.

Answer 1

$\text{Tyndall effect}$:- Tyndall effect is a scattering of light when a light beam is passed through a colloidal.

$Example$;- Shining a flashlight beam into a glass of milk is an excellent demonstration of Tyndall effect.

$\text{Electrophoresis and electro-osmosis}$

• In $electrophoresis$, solid particles (macromolecule like nucleic acids or protein) is moved using an electric field. But in electro-osmosis, a liquid is moving.
• In $electrophoresis$, the support solid material is a gel. But in electro-osmosis, it can be a gel, membrane, capillary, etc.
