Question

$Ba \left( NO _3\right)_2( aq )+2 NaIO _3( aq ) \rightarrow Ba \left( IO _3\right)_2(s)+2 NaNO _3( aq )$
image
${\left[ NaIO _3\right]=\frac{6}{300}

$3.95$

Vedclass · Answer

$Ba \left( NO _3ight)_2( aq )+2 NaIO _3( aq ) ightarrow Ba \left( IO _3ight)_2(s)+2 NaNO _3( aq )$
image
${\left[ NaIO _3ight]=\frac{6}{300}=2 	imes 10^{-2} M }$
$Ba \left( IO _3ight)_2(s) ightleftharpoons Ba ^{2+}+2 IO _3^{-}$
$\left(2 	imes 10^{-2}+2 sight)$
$K _{ sp }=\left[ Ba ^{+2}ight]\left[ IO _3^{-}ight]^2$
$1.58 	imes 10^{-9}=\left[ Ba ^{+2}ight] 	imes\left(2 	imes 10^{-2}ight)^2$
${\left[ Ba ^{+2}ight]= s =3.95 	imes 10^{-6} M }$
$X =3.95$
