Short Answer

Expert verified

The concentration of ${Ba}^{2 +}$ in a $0.001 M {({CH}_{3})}_{4} {NIO}_{3}$ solution saturated with $Ba {({IO}_{3})}_{2}$ is $6.6 \times 10^{- 7} M$

Step by step solution

Step 1:Finding the activity coefficient of aqueous solution Ba2+ and IO3-.

In the given problem, we need to find the activity coefficient along with concentration of ${Ba}^{2 +}$ in a $0.001 M {({CH}_{3})}_{4} {NIO}_{3}$ solution saturated with $Ba {({IO}_{3})}_{2}$ .

The solubility of $Ba {({IO}_{3})}_{2}$ is not quite expressed. So we will assume that $Ba {({IO}_{3})}_{2}$ contributes negligible ${IO}_{3}^{-} to 0.100 M {({CH}_{3})}_{4} {NIO}_{3}$ .

$c ({IO}_{3}^{-}) = 0.1 M$

From the Table $8 - 1$ , we can know that the values are,

$γ ({Ba}^{2 +}) = 0.380 γ ({IO}_{3}^{-}) = 0.775$

Finding the concentration of Ba2+in a 0.001M(CH3)4NIO3 solution saturated with Ba(IO3)2 using equilibrium constant equation.

Now, we will use equilibrium constant equation,

$K_{sp} = 1.5 \times 10^{- 9} K_{sp} = (c ({Ba}^{2 +}) γ ({Ba}^{2 +})) \times (c^{2} ({IO}_{3}^{-})) 1.5 \times 10^{- 9} = (c ({Ba}^{2 +}) \times 0.380) \times (0 . 1^{2} \times 0 . 775^{2}) c ({Ba}^{2 +}) = 6.6 \times 10^{- 7} M$

Thus the concentration of ${Ba}^{2 +}$ in a $0.001 M {({CH}_{3})}_{4} {NIO}_{3}$ solution saturated with $Ba {({IO}_{3})}_{2}$ is $6.6 \times 10^{- 7} M$
