Which of following aqueous mixture of CH_(3)COOHand CH_(3)COONawill have maximum buffer capacity?

Answer»

`[CH_(3)COOH] = 1M, [CH_(3)COONA] = 10^(-3)M`
`[CH_(3)COOH] = 0.1 M, [CH_(3)COONa] = 10^(-5)M`
`[CH_(3)COOH] = 0.1 M, [CH_(3)COONa] = 0.1 M`
`[CH_(3)COOH] = 0.001M, [CH_(3)COONa] = 0.1 M`

Solution :ACIDIC buffer having pH= pKa has maximum buffer capacity
