Question
$$KF$$ combines with $$HF$$ to form $$KH{F_2},$$ The compound contains the species.
A.
$${K^ + },{F^ - }{\text{and}}\,{H^ + }$$
B.
$${K^ + },{F^ - }{\text{and}}\,HF$$
C.
$${K^ + }\,{\text{and }}{\left[ {H{F_2}} \right]^ - }$$
D.
$${\left[ {KHF} \right]^ + }\,{\text{and}}\,{F^ - }$$
Answer :
$${K^ + }\,{\text{and }}{\left[ {H{F_2}} \right]^ - }$$
Solution :
$$\eqalign{
& KF + HF \to KH{F_2} \rightleftharpoons {K^ + } + {\left( {H{F_2}} \right)^ - } \cr
& \cr} $$
