Out of sulphur sol and proteins, which one forms multimolecular colloids?

Explanation

To determine which of the two substances, sulfur sol or proteins, forms multimolecular colloids, we can follow these steps:

### Step 1: Define Multimolecular Colloids
Multimolecular colloids are colloidal systems formed by the aggregation of small molecules or particles that come together to form larger particles within the colloidal size range. These larger particles are made up of many smaller units.

### Step 2: Analyze Sulfur Sol
Sulfur sol consists of small sulfur particles dispersed in a liquid. These small particles can aggregate to form larger colloidal particles. Therefore, sulfur sol can be classified as a multimolecular colloid because it is formed by the aggregation of smaller sulfur molecules.
