1.	If an acid-base reaction HA(aq)+B^(-)(aq)hArr HB(aq)+A^(-)(aq) has K_(aq)=10^(-4).how many of the following statements are true? (i) HB is stronger acid than HA (ii) HA is stronger acid than HB (iii) HA and HB have the same acidic strength (iv) B^(-) stronger base than A^(-) (v) A^(-) is stronger base than B^(-) (vi) B^(-) and HB are conjugate acid-base pair (vii) A^(-) is the conjugate base of acid HA. (viii)HA can beHSO_(4)^(-) and HB can be HCOOH. A^(-) can be F^(-) and B^(-) can be CN^(-)
Answer» Solution :`HA(aq)+B^(-)(aq)hArr HB(aq)+A^(-)(aq)""K_(eq)=10^(-4)` `K_(eq)` is very small .So reaction SHIFT in BACKWARD direction. `(1) HB` is more stronger acid than `HA` (2) `A^(-)` is more stronger base than `B^(-)` (3) `B^(-)` and `HB` are conjugate acid-base PAIR.
