Consider the three solutions of 1 M concetration (1) Sodium acetate (CH_3COONa) (2)Acetic acid +Sodium acetate (CH_3COOH+ CH_3COONa) (3)Acetic acid (CH_3COOH) pH of these solutions will lie in the following sequence:

Answer»

<P>` 3 lt 2 lt 1 `
` 2 lt 1 lt 3 `
` 1 lt 2 lt 3 `
` 3 lt 1 lt 2 `

Solution :For `CH_3 COONa , PH GT 7`
(2) For buffer `, pH =P^(KA) `
(3)For acid, pH =` (P^(Ka))/( 2) `
