3. Which solution would have the lowest [OH-]?And why?
a. pure water
b. 0.50 M NH3
c. 0.50 M HCl
d. 0.10 M NaOH
e. 0.10 M NaCl ?
回答 (1)
The answer: c. 0.50 M HCl
Explanation:
• a and e are neutral, and thus [OH⁻] = 1 × 10⁻⁷ M
• b and d are basic, and thus [OH⁻] > 1 × 10⁻⁷ M
• c is acidic, and thus [OH⁻] < 1 × 10⁻⁷ M
