Question:

Which of the following is a characteristic of a multi-molecular colloid?

Options:

Large number of molecules combine to form a particle of colloidal size

A large number of atoms aggregate to form a particle of colloidal size

Starch solution is an example of multi-molecular colloid

Multi-molecular colloids are normally of the lyophilic type

Correct Answer:

A large number of atoms aggregate to form a particle of colloidal size

Explanation:

In these type of colloidal solution, several atoms or tiny molecules group together to produce colloidal-sized particles, which are often of the lyophobic variety. As starch solution provides an illustration of lyophilic colloids rather than multi-molecular colloids, it is not a suitable comparison.
