Question

Which of the following is a buffer solution? (A)  NaOH+NaCl  (B)  NaOH+Na2CO3  (C)  CH3COOH+CH3COONa  (D) None of the above

Buffer solutions are obtained, when a weak acid is mixed with its conjugate base or a weak base is mixed with its conjugate acid. Hence, solution of acetic acid and sodium acetate is a Buffers solution.

Q. Which of the following is a buffer solution?
