Solubility of $BaF_2$ in a solution of $Ba(NO_3)_2$ will be represented by the concentration term?

A

$[Ba^{+2}]$

B

$2[F^{\circleddash}]$

C

$\frac{1}{2}[F^{\circleddash}]$

D

$2[NO_3^{\circleddash}]$

Solution

$BaF _2 \longrightarrow \underset{s+x}{Ba _{( aq )}^{+2}}+\underset{(2s )}{2 F _{( aq) }^{-}}$

$\underset{xM}{Ba \left( NO _{3 M }\right)_2} \longrightarrow \underset{x+s}{Ba _{( aq )}^{+2}}+2 NO _{3( aq )}^{-}$

Where $S =$ solubility of $BaF _2$

$\therefore \quad K _{ sp }=\left[ Ba ^{+2}\right]\left[ F ^{-}\right]^2$

$\therefore \quad\left[ F ^{-}\right]=\sqrt{\frac{ K _{ sp }}{\left[ Ba ^{+2}\right]}}$

$\therefore \quad$ Solubility of $BaF _2=\frac{1}{2} \times(2 s )$

$=\frac{1}{2} \times\left[ F ^{-}\right]$
