Answer» Solution :Anltydrous `HF` is stabiliused dueto intermolecular H-bonding and is less DISSOCIATED `AIF_(3)` is soluble in `HF` in the PRESSENCE of `KF` dueto THEFORMATIONOF `[AIF_(6)]^(3-): 3KF + AIF_(3) rarr K_(3)[AIF_(6)]` `BF_(3)` displacesour `F^(Theta) ` from `[AIF_(6)]^(3-)` because it is more acidic than`AIF_(3)` `K_(3) [AIF_(6)] + BF_(3) rarr AIF_(3) DARR+ 3KBF_(4)` |
