Which buffer solution out of the following will have `pH gt 7`?

A

`CH_(3)COOH +CH_(3)COONa`

B

`HCOOH +HCOOK`

C

`CH_(3)COONH_(4)`

D

`NH_(4)OH +NH_(4)Cl`

Text Solution

Verified by Experts

The correct Answer is:
D
For basic buffers
`pOH =pK_(b) + log. (["salt"])/(["base"])`
`1//10 lt ["salt"]//["base"] lt 10 `
So pOH = `pK_(b) pm 1 `
For weak bases `pK_(b) lt 5`
So `pOH lt 6 or pH gt 8`
