Which of the following is useful to verify the charge on colloidal particles?
Show Hint
In colloidal chemistry, electrophoresis is an important method to measure the zeta potential and verify the charge on colloidal particles.
Updated On: Mar 13, 2025
- Electrophoresis
- Gold number
- Brownian motion
- Bredig's Arc experiment
Hide Solution
Verified By Collegedunia
The Correct Option is A
Solution and Explanation
Understanding the concept of electrophoresis:
Electrophoresis is a technique used to study the charge on colloidal particles. When an electric field is applied, colloidal particles move towards the oppositely charged electrode, which helps in determining the nature of the charge (positive or negative) on the colloidal particles.
The other options, such as Gold number, Brownian motion, and Bredig's Arc experiment, are not primarily used for verifying the charge of colloidal particles.
Thus, the correct answer is option (1).

Top Questions on Organic Chemistry- Some Basic Principles and Techniques
- Given below are two statements :
Statement I : The boiling point of three isomeric pentanes follows the order
n-pentane > isopentane > neopentane
Statement II : When branching increases, the molecule attains a shape of sphere. This results in smaller surface area for contact, due to which the intermolecular forces between the spherical molecules are weak, thereby lowering the boiling point.
In the light of the above statements, choose the most appropriate answer from the options given below :- NEET (UG) - 2024
