Question
Chemistry Question on Classification of Colloids
Multimolecular colloids are present in
A
Soap solution
B
Sol of proteins
C
Sol of gold
D
All of these
Answer
Sol of gold
Explanation
Solution
When a large number of small particles (dispersion phase) aggregate to form a large size molecule or particle having the size in the colloidal range, it known as Multimolecular colloids. Here, the atoms or particles are held together by weak van der Waals force of attraction. For example, gold sol contains particles of various sizes having several atoms. Another example is sulfur solution. Sol of protein are present in macro molecular colloids and soap solution is present in associated colloids.
