Question

Which of the following colloids resemble the true solutions?

• A. Macromolecular colloids
• B. Micelles
• C. Micromolecular colloids
• D. Lyophobic colloids

Hint:

Macromolecular colloids behave similarly to true solutions and do not exhibit Tyndall effect due to their small particle size.

Answer 1

The Correct Option is A

Macromolecular colloids are colloidal solutions with large molecules (such as proteins, starch, etc.) that resemble true solutions. They have particles that are large enough to form a stable suspension, but small enough to exhibit properties of true solutions. These colloids do not scatter light, similar to true solutions. Thus, the correct answer is Option (A).
