Question

In these colloids, a large number of small atoms or smaller molecules of a substance aggregate to form colloidal particles having size in colloidal range. These colloids are known as:

• A. multimolecular colloids
• B. macromolecular colloids
• C. associated colloids
• D. lyophilic colloids

Answer 1

Answer: (A)

multimolecular colloids

• On dissolution, a large number of atoms or smaller molecules of a substance aggregate together to form species having a size in the colloidal range $(1–1000nm).$ These are called multimolecular colloids.
  

• Gold sol, Sulphur sol are examples of multimolecular colloids.
