Vedclass · Answer

(C) $KF$ reacts with $HF$ to form potassium hydrogen difluoride $(KHF_2)$.In the solid state,$KHF_2$ is an ionic compound consisting of potassium ions $(K^{+})$ and hydrogen difluoride ions $([HF_2]^{-})$.The $[HF_2]^{-}$ ion is formed due to strong hydrogen bonding between the fluoride ion $(F^{-})$ and the hydrogen fluoride molecule $(HF)$: $F^{-} \cdots H-F \rightarrow [F-H-F]^{-}$.Therefore,the compound contains $K^{+}$ and $[HF_2]^{-}$ ions.

$KF$ combines with $HF$ to form $KHF_2$. Which of the following species are present in this compound?
