Transcribed Image Text:**How many of these compounds are strong electrolytes?**
A. HCl(aq)
B. HClO(aq)
C. CH₃COOH (acetic acid)
D. C₂H₆O (ethanol)
E. KOH
F. KCl(aq)
Options:
- O 1
- O 4
- O 2
- O 3
**Explanation:**
- **HCl(aq)**: Strong electrolyte. Hydrochloric acid dissociates completely in water.
- **HClO(aq)**: Weak electrolyte. Hypochlorous acid is a weak acid and does not dissociate completely.
- **CH₃COOH (acetic acid)**: Weak electrolyte. Acetic acid is a weak acid and only partially dissociates in water.
- **C₂H₆O (ethanol)**: Non-electrolyte. Ethanol is a non-electrolyte and does not dissociate in water.
- **KOH**: Strong electrolyte. Potassium hydroxide dissociates completely in water.
- **KCl(aq)**: Strong electrolyte. Potassium chloride dissociates completely in water.
The correct answer is 3 (HCl(aq), KOH, and KCl(aq)).
