Which of the following is incorrectly matched?
- A Multi molecular colloid \(-\mathrm{S}_8\)
- B Macro molecular colloid - enzyme
- C \(\mathrm{As}_2 \mathrm{~S}_3\) sol - positively charged sol
- D Starch sol - lyophilic sol
Answer & Solution
Correct Answer
(C) \(\mathrm{As}_2 \mathrm{~S}_3\) sol - positively charged sol
Step-by-step Solution
Detailed explanation
Sulphur sol consists of particles containing a thousand or more \(\mathrm{S}_8\) sulphur molecule hence it is the multi molecular colloid. Enzymes and proteins are example of macromolecular that exist naturally. Starch forms a lyophilic solution with water when heated.…
