Which from following statements is NOT true about lyophilic colloids?

A The particles of dispersed phase have greater affinity for the dispersion medium.
B These are reversible.
C These are self stabilized.
D Coagulation occurs even by adding very small amount of electrolytes.

Verified Solution

Answer & Solution

Correct Answer

(D) Coagulation occurs even by adding very small amount of electrolytes.

Step-by-step Solution

Detailed explanation

In lyophilic colloids, the particles of dispersed phase have a great affinity for the dispersion medium. They are reversible and self-stabilized colloids. Addition of large amount of electrolytes causes precipitation or coagulation of lyophilic sols.

Apply the relevant identity from the chapter and substitute the values established in the previous step, keeping the original constraint in view.

Use the simplified expression to isolate the unknown, then plug the result back into the question setup to confirm the working is internally consistent.

Cross-check against a boundary or limiting case. Both the dimensional balance and the qualitative behaviour at the extreme should agree with the candidate answer.

Combine the steps above to identify the correct option. The remaining choices each fail at least one of the consistency, dimensional, or boundary checks.
