Which of the following is a lyophilic colloid?
- A.Sulfur sol
- B.Gold sol
- C.Starch sol
- D.Metal sulfide sol
Show correct answer & step-by-step solution
Correct answer: C — Starch sol
Solution
- Lyophilic colloids are solvent-loving and formed by substances like starch, gum, or proteins.
- Lyophobic colloids are solvent-hating and include metal sols or metal sulfides.
- Starch is a classic example of a lyophilic colloid.
- Hence the answer is (C).
