MCQ
An acidic buffer solution can be prepared by mixing the solution of
  • sodium acetate and acetic acid
  • B
    ammonium chloride and ammonium hydroxide
  • C
    sulphuric acid and sodium hydroxide
  • D
    sodium chloride and sodium hydroxide

Answer

Correct option: A.
sodium acetate and acetic acid
a
A mixture of acetic acid and sodium acetate acts as a buffer since sodium acetate is the conjugate base of acetic acid. Its $pH$ around $4.75$.
