Question

The conversion of a sol to a gel is called

• A. Solution
• B. Gelation
• C. Filtration
• D. Precipitation

Hint:

Sol to gel:
- Gelation is the process.
- Examples: Jelly, gelatin, curd.
- Gels have a semi-solid structure.

Answer 1

The Correct Option is B

Step 1: Understanding the Question:
This question tests knowledge of colloidal chemistry.

Step 2: Detailed Explanation:
The conversion of a sol (liquid colloidal solution) to a gel (semi-solid) is called Gelation (B).
Gelation occurs when the dispersed particles form a network that traps the liquid.
Examples: Jelly, curd.
Other terms:
- Solution (A): A homogeneous mixture of solutes.
- Filtration (C): Separation of solids from liquids.
- Precipitation (D): Formation of a solid from a solution.
Thus, gelation is the sol to gel conversion.

Step 3: Final Answer:
Thus, the conversion of a sol to a gel is called gelation, which corresponds to option (B).
