In electrophoresis, what property of ions is primarily utilized for separation?

Step 1: Understand that electrophoresis is a technique used to separate charged particles, like ions.
Step 2: Recognize that ions have a positive or negative charge.
Step 3: Learn that when an electric field is applied, ions will move towards the opposite charge (positive ions move to negative, and negative ions move to positive).
Step 4: Realize that the speed and distance each ion travels depend on its charge and size.
Step 5: Conclude that the primary property used for separation in electrophoresis is the charge of the ions.

Charge of Ions – Electrophoresis separates ions based on their charge, which determines their movement in an electric field.
Migration in Electric Field – The process relies on the ability of charged particles to migrate towards the electrode of opposite charge.
