Vedclass · Answer

(C) buffer solution is formed by a mixture of a weak acid and its conjugate base, or a weak base and its conjugate acid.In option $A$, $NH_3$ (weak base) and $HCl$ (strong acid) in a $2:1$ ratio result in $NH_4Cl$ and $NH_3$, forming a basic buffer.In option $B$, $CH_3COOH$ (weak acid) and $NaOH$ (strong base) in a $2:1$ ratio result in $CH_3COONa$ and $CH_3COOH$, forming an acidic buffer.In option $C$, $NaOH$ and $CH_3COOH$ in a $1:1$ ratio undergo complete neutralization to form $CH_3COONa$ (a salt of a weak acid and strong base), which does not act as a buffer.In option $D$, $NH_4Cl$ and $NH_3$ form a standard basic buffer.
