$CH_3COOH + NaOH$ ($2:1$ mole ratio)

Vedclass · Answer

(B, C) buffer solution is formed by a mixture of a weak acid and its salt with a strong base,or a weak base and its salt with a strong acid.Option $B$: $NH_4OH$ (weak base) + $HCl$ (strong acid) in $2:1$ mole ratio results in $NH_4Cl$ (salt) and remaining $NH_4OH$. This forms a basic buffer.Option $C$: $CH_3COOH$ (weak acid) + $NaOH$ (strong base) in $2:1$ mole ratio results in $CH_3COONa$ (salt) and remaining $CH_3COOH$. This forms an acidic buffer.Both $B$ and $C$ act as buffer solutions.

Which of the following mixtures act$(s)$ as a buffer solution?
