Question
Transcribed Image Text:**Question:**
Which of the following is a strong acid in aqueous solution?
**Options:**
- ( ) HOCH₂CH₂OH
- ( ) Ba(OH)₂
- ( ) CH₃COOH
- ( ) NH₃
- ( ) HClO₄
**Explanation:**
The question asks to identify the strong acid from the given chemical compounds in aqueous solution. Let's briefly define each compound:
1. **HOCH₂CH₂OH (Ethylene glycol):** This is an alcohol, not an acid.
2. **Ba(OH)₂ (Barium hydroxide):** This is a strong base, not an acid.
3. **CH₃COOH (Acetic acid):** This is a weak acid.
4. **NH₃ (Ammonia):** This is a weak base.
5. **HClO₄ (Perchloric acid):** This is a strong acid.
The correct answer is HClO₄, as it is known to completely dissociate in aqueous solutions, making it a strong acid.
