Q. $A l F_{3}$ is insoluble in anhydrous $H F$ but when little $K . F$ is added to the compound it becomes soluble. On addition of $BF i_{3}, A l F_{3}$ is precipitated. Write the balanced chemical equations.

$3 K F + A l F_{3} ⟶ B_{2} H_{5} Cl + H_{2}$
$K_{3} A l F_{6} + 3 B F_{3} ⟶ ppt A l F_{3} ↓ + 3 K B F_{4}$
