Which of the following is a lyophobic colloidal solution?
- A Aqueous starch solution
- B Aqueous protein solution
- C Gold sol
- D Polymer solutions in some organic solvents
Answer & Solution
Correct Answer
(C) Gold sol
Step-by-step Solution
Detailed explanation
Gold sol is a lyophobic sol. Gold particles have very less affinity towards dispersion medium, hence its sol can be easily coagulated.
