Q. Consider the following solutions of equal concentrations $A = NH_{4}Cl$ $B = CH_{3}COONa$ $C = NH_{4}OH$ $D = CH_{3}COOH$ A buffer solution can be obtained by mixing equal volumes of
A) $C$ and $D$
B) $A$ and $B$
C) $A$ and $C$
D) $C$ and $D$
Explanation
(c)
A solution with reverse acidity or basically is known as buffer solution. It is of two types :
(I)Acidic buffer solution : A mixture of weak acid and its salt with strong base
e.g., $CH_{3}COOH + CH_{3}COONa$
(II)Basic buffer solution : A mixture of a weak base and its salt with strong acid.
e.g., $NH_{4}OH + NH_{4}Cl$
