Q. Which of the following $1 : 1$ mixture will act as buffer solution?

Jharkhand CECEJharkhand CECE 2005

Solution:

Buffer is a mixture of weak acid with its salt with strong base or mixture of weak base and its salt with strong acid:
[a] $HCl + NaOH$ is not buffer because both are strong acid and strong base.
[b] $KOH + CH _{3} COOH$ is not buffer because they do not have common ion.
[c] $CH _{3} COOH + NaCl$ is not buffer because they do not have common ion.
[d] $CH _{3} COOH + CH _{3} COONa$ are buffer because $CH _{3} COOH$ is weak acid and $CH _{3} COONa$ its salt with strong base $( NaOH )$.
