- (A) glucose
- (B) urea
- (C) ephedrine
- (D) sodium chloride
- (E) sucrose
Click below for Answer and Explanation:
Answer
(C) Ephedrine
Explanation:
- Electrolytes form ions in water and conduct electricity.
- Strong electrolytes (e.g., sodium chloride) → fully ionize.
- Weak electrolytes (e.g., ephedrine) → partially ionize.
- Non-electrolytes (e.g., glucose, urea, sucrose) → don’t ionize at all.
So, ephedrine is the correct weak electrolyte here.
