Given : Strength of acid : HA(aq)gtHB(aq)gtHC(aq) Which is Incorrect statement ?

Answer»

Strength of conjugate base: `A^(-)(aq)LTB^(-)(aq)ltC^(-)(aq)`.
Hydrolysis constant : `K_(h)(A^(-))ltK_(h)(B^(-))ltK_(h)(C^(-))`
| Enthalpy of neutralisation with `NaOH|HA(aq)gtHB(aq)GTHC(aq)`.
BOILING point of SOLUTION : `HA(aq)lt HB(aq)lt HC(aq)`.

Solution :Strength of conjugate acid `uarr` strength of conjugate base `darrK_(h)=(K_(W))/(K_(a)),K_(a)uarrK_(h)darr`
|Enthalpy of neutralisation| `uarr`
`K_(a)uarralphauarr"Vant hoff factor "v uarr`
`DeltaT_(b)uarrT_(b)uarr`
