Which from following mixtures in water acts as a basic buffer?

Options

  1. ANH ₄ OH + NH ₄ Cl
  2. BC ₆ H ₅ COOH + C ₆ H ₅ COONa
  3. CHCOOH + HCOOK
  4. DCH ₃ COOH + CH ₃ COONa

Correct answer

A. NH ₄ OH + NH ₄ Cl

Step-by-step solution

Basic buffer is the mixture of weak base and its salt with strong acid. In option A , NH ₄ OH is weak base and NH ₄ Cl is salt of strong acid and weak base. Hence, NH ₄ OH + NH ₄ Cl is basic buffer. Other options are examples of acidic buffer.
