(a)

Interpretation Introduction

Interpretation:

The pictures of electrophoretic and electro osmotic process with anode, cathode, injector, detector, and flow should be drawn.

Concept introduction:

Electrophoresis:

The movement of charged particles due to the applied electrical field is known as electrophoresis.

Electro osmosis:

The movement of charged medium due to the applied electrical field is known as electrophoresis.

(b)

Interpretation Introduction

Interpretation:

The migration times of ${\text{Cl}}^{\text{-}}$, ${\text{I}}^{\text{-}}$, and ${\text{Br}}^{\text{-}}$ should be comparatively explained.

Concept introduction:
