Questions & Answers

Q: How do colloidal particles acquire electrical charge?

Colloidal particles acquire electrical charge through the process of adsorption, in which they attract and surround ions present in the dispersion medium.

Q: What factors influence the electrical properties of colloidal dispersions?

The electrical properties of colloidal dispersions are influenced by the existence of electrical charge on the colloidal particles, which can be affected by the dispersion medium and the dispersed phase.

Q: Can the addition of certain substances cause colloidal particles to acquire a charge?

Yes, adding substances that dissociate into ions, such as electrolytes, can cause colloidal particles to acquire a charge through adsorption of the ions.

Q: What determines whether colloidal particles acquire a positive or negative charge?

The charge acquired by colloidal particles depends on the nature of the added substances and the presence of common ions. Common ions can influence the charge acquired by the colloidal particles.

Summary & Key Takeaways

• Colloidal dispersions have electrical charge on the colloidal particles, which results in the acquisition of a positive or negative charge.

• The electrical properties of the colloidal solution are associated with the existence of electrical charge on the colloidal particles, which can be influenced by the dispersion medium and the dispersed phase.

• Adding certain substances to a solution can cause the colloidal particles to acquire a positive or negative charge, depending on the presence of common ions.
