$$KF$$ combines with $$HF$$ to from $$KHF_{2}$$ The compound contains the species:

A$$K^{+},F^{-} \;and\; H^{+}$$
B$$K^{+},F^{-}\; and \;HF$$
C$$K^{+}\;and\;[HF_{2}]^-$$
Correct Answer
D$$[KHF]^{+}\;and\;F_{2}$$

Solution

$$KF\rightarrow K^ ++F^ - $$
$$F^{ - }+HF\rightarrow \left[ HF_ 2 \right] ^{ - }$$
$$KHF_{ 2 }$$ is formed by the ions, $${ K }^{ + }$$ and $${ HF }_{ 2 }^{ - }$$. $${ HF }_{ 2 }$$ is a covalent compound. Hydrogen bonding exists between $$F^-$$ and $$HF$$.
