The `pH` of blood is 7.4 . What is the ratio of `[(HPO_(4)^(2-))/(H_(2)PO_(4)^(-))]` in the blood. `pK_(a)(H_(2)PO_(4)^(-))=7.1`

A

`2:1`

B

`1:2`

C

`3:1`

D

`1:3`

Text Solution

Verified by Experts

The correct Answer is:
1
`{:H_(2)PO_(4)^(-),hArr,HPO_(4)^(2-),+,H^(+):}`
`8xx10^(-8)=((HPO_(4)^(2-))/(H_(2)PO_(4)^(2-)))xx4xx10^(-8)" "rArr" "((HPO_(4)^(2-))/(H_(2)PO_(4)^(2-)))=(2)/(1)`
