Question
Which of the following is/are correct regarding buffer solution ?
Options
A.It contains weak acid and its conjugate base
B.It contains weak base and its conjugate acid
C.It shows large change in pH on adding small amount of acid or base.
D.All of the above.
Solution
(A) A buffer solution is a solution which contains weak acid and its conjugate base. it is acidic buffer.
(B) Basic buffer contains weak base and its conjugate acid.
(C) is wrong because it does not show change in pH on adding small amount of acid or base.
(D) is wrong ; all the above statements are not correct.
