Answer 1

electrophoresis using u-tube
it's May be wrong
U-tube in a electrochemical cell m h

Answer 2

Answer:

(1) Electrophoresis : The movement of colloidal particles under an applied electric potential (or field) is called electrophoresis.

(2) Explanation:Two platinum electrodes are dipped in a colloidal solution filled in U tube. When an electric field (potential) is applied across the electrodes, the charged colloid particles migrate towards oppositely charged electrodes.

(3) Applications :

(a) To decide the electrical charge on the colloidal particles

(b) To separate colloidal particles and obtain a pure true solution.

(c) Since the components of colloidal particles in a mixture migrate with different rates, they can be separated.

(d) The rate of migration of colloidal particles can be measured.
