An example for hydrophobic sol among the following is
- A gum solution
- B arsenic sulphide solution
- C starch solution
- D protein solution
Answer & Solution
Correct Answer
(B) arsenic sulphide solution
Step-by-step Solution
Detailed explanation
Arsenic sulphide solution \(\left(\mathrm{As}_2 \mathrm{~S}_3 \mathrm{~S}^{2-}\right)\) is a hydrophobic solution i.e. it has poor or zero affinity towards dispersion medium \(\left(\mathrm{H}_2 \mathrm{O}\right)\). Whereas, solution of gum, starch and protein are individually…
