For the aqueous solution of a salt of a weak acid abd a weak base,

A

`K_(h)=sqrt(h)/(1-h)`

B

`sqrt(K_(h))=(h^(2))/(1-h)`

C

`sqrt(K_(h))=(h)/(1-h)`

D

`K_(h)=(h)/(1-h)`

Text Solution

Verified by Experts

The correct Answer is:
C
`{:(B^(+)(aq.)+,A^(-)(aq.)+,H_(2)O,hArrBOH,+HA),("Initial",C,C,0,0),("Equilibrium",C(1-h),C(1-h),Ch,Ch):}`
`K_(h) = ([BOH][HA])/([B^(+)][A^(-)])= (Ch.Ch)/(C(1-h)C(1-h))= (h^(2))/((1-h)^(2))`
`sqrt(K_(h)) = (h)/(1-h)`
