For preparing a buffer solution of pH 6 ...

For preparing a buffer solution of `pH 6` by mixing sodium accetate and acetic, the ratio of the concentration of salt and acid should be `(K_(a)=10^(-5))`

A

`1:10`

B

`10:1`

C

`100:1`

D

`1:100`

Text Solution

Verified by Experts

The correct Answer is:
B
`6=-log10^(-5)+log""(["salt"])/(["acid"])=5+log""(["salt"])/(["acid"])`
`log""(["salt"])/(["acid"])" must be 1. ":.(["salt"])/(["acid"])=(10)/(1)or10:1`
