Question
Choose the most correct answer:
Which of the Na following is a buffer solution?
Options
CH3COONa + NaCl in water
CH3COOH + HCl in water
CH3COOH + CH3COONa in water
HCl + NH4Cl in water

Solution
CH3COOH + CH3COONa in water
Explanation:
A buffer solution is a water-based mixture of a weak acid and its conjugate base. It could potentially be a combination of a weak base and its conjugate base.
In the given, only option C has weak acid CH3COOH and its conjugate base CH3COONa
Option A has a strong base and its conjugate base.
Options D and B are not buffer solutions as they contain strong acids HCl.
