Question: In electrophoresis, what property of ions primarily determines their movement?

Options:

Correct Answer: Charge

Solution:

The movement of ions in electrophoresis is primarily determined by their charge; positively charged ions move towards the cathode.

In electrophoresis, what property of ions primarily determines their movement?

Step 1: Understand that electrophoresis is a technique used to separate ions based on their movement in an electric field.
Step 2: Recognize that ions can be positively charged (cations) or negatively charged (anions).
Step 3: Know that in an electric field, positively charged ions move towards the negative electrode, called the cathode.
Step 4: Realize that the charge of the ions is the main factor that determines their direction and speed of movement during electrophoresis.

Charge of Ions – The movement of ions in an electric field is primarily influenced by their charge, with positively charged ions moving towards the cathode and negatively charged ions moving towards the anode.
Electrophoresis Mechanism – Electrophoresis is a technique that separates charged particles based on their movement in an electric field, which is influenced by their charge and size.
