medium
$BF_3$ on hydrolysis forms
A
$H_3BO_3$
B
$HBF_4$
C
both $(A)$ and $(B)$
D
none of these
Solution
$\mathrm{BF}_{3}$ Partial hydrolysis.
$\mathrm{BF}_{3}+3 \mathrm{H}_{2} \mathrm{O} \rightarrow \mathrm{B}(\mathrm{OH})_{3}+3 \mathrm{HF}$
$3 \mathrm{HF}+3 \mathrm{BF}_{3} \rightarrow 3 \mathrm{H}\left[\mathrm{BF}_{4}\right]$
