`AlF_3` is soluble in HF only in presence of KF. It is due to the formation of-

A

`K_3[AlF_6]`

B

`AlH_3`

C

`K[AlF_3H]`

D

`K_3[AlF_3H_3]`

Text Solution

Verified by Experts

The correct Answer is:
A
`AIF_3 + 3KF overset(HF)toK_3[AIF_6]`
The maximum coordination number shown by `Al^(3+)` is 6 and thus it can form `AIF_6^(3-)` ion.
