KF combines with HF to form `KHF_(2).` The compound contains the species

A

`K^(+),F^(-) and H^(+)`

B

`K^(+),F^(-) and HF`

C

`K^(+) and [HF_(2)]^(-)`

D

`[KHF]^(+) and F_(2)`

Text Solution

Verified by Experts

The correct Answer is:
C
The fluoride ion, by a process of hydrogen bonding, forms the anion, `HF_(2)^(-)`. The compound is written as `K^(+)[HF_(2)]^(-)`.
