A) Oxidation of \[HF\]
B) Electrolysis of \[KF\]
C) Electrolysis of fused \[KH{{F}_{2}}\]
D) Decomposition of \[Hg{{F}_{2}}\]
Correct Answer: C
Solution :
\[KH{{F}_{2}}\,\to \,KF+HF\] \[KF\,\to \,{{K}^{+}}+{{F}^{-}}\] At cathode : \[{{K}^{+}}+{{e}^{-}}\,\to \,K\] \[2K+2HF\,\to \,2KF+{{H}_{2}}\] At anode : \[{{F}^{-}}\,\to \,F+{{e}^{-}}\] \[F+F\,\to \,{{F}_{2}}\]
