Question:
The pOH of a 0.0235 M hydrochloric acid will be ________.
The pOH of a 0.0235 M hydrochloric acid will be ________.
Show Hint
Low pH (Acidic) corresponds to high pOH.
Updated On: Apr 17, 2026
- 1.629
- 12.371
- 2.2
- 11.8
Show Solution
Verified By Collegedunia
The Correct Option is B
Solution and Explanation
Step 1: Concept
Relation between pH and pOH ($pH + pOH = 14$).
Step 2: Calculation of pH
$HCl$ is a strong acid, so $[H^+] = 0.0235$ M.
$pH = -\log(0.0235) \approx 1.629$.
Step 3: Calculation of pOH
$pOH = 14 - pH$
$pOH = 14 - 1.629 = 12.371$.
Step 4: Conclusion
Hence, the pOH is 12.371.
Final Answer:(B)
Relation between pH and pOH ($pH + pOH = 14$).
Step 2: Calculation of pH
$HCl$ is a strong acid, so $[H^+] = 0.0235$ M.
$pH = -\log(0.0235) \approx 1.629$.
Step 3: Calculation of pOH
$pOH = 14 - pH$
$pOH = 14 - 1.629 = 12.371$.
Step 4: Conclusion
Hence, the pOH is 12.371.
Final Answer:(B)
