MCQ
1M NaCl and 1M HCl are present in an aqueous solution . The solution is:
- ANot a buffer solution with pH < 7
- BNot a buffer solution with pH > 7
- CA buffer solution with pH < 7
- DA buffer solution with pH > 7
✓
Answer
- Not a buffer solution with pH < 7
Explanation:
Buffer can accept and donate protons at the same time and HC1is an acid. So, it has pH < 7.
So, this is not a buffer and the solution will be acidic.
