Which of the following would produce a buffer solution when mixed in equal volumes?
Options
- A1 M CH ₃ COOH and 0.5 M NaOH
- B1 M CH ₃ COOH and 0.5 M HCI
- C1 M NH ₄ OH and 0.5 MNaOH
- D1 M NH ₄ Cl and 0.5 M HCl
Correct answer
A. 1 M CH ₃ COOH and 0.5 M NaOH
Step-by-step solution
CH ₂ COOH + HONa CH ₃ COONa + H ₂ O Weak acid CH ₂ COOH and its salt with strong base CH , COONa acts as acidic buffer.
