Redox Reactions And Electrochemistry Ques 712

Question: Equivalent conductivity of $B a C l_{2}, H_{2} S O_{4}$ and HCl are $y_{1}, y_{2}$ and $y_{3} S, c m^{- 1} e q^{- 1}$ at infinite dilution. If conductivity of saturated $B a S O_{4}$ solution is $y, S, c m^{- 1},$ then find $K_{s p}$ of $B a S O_{4}$ .

Options:

A) $\frac{y^{2}}{{(y_{1} + y_{2} - y_{3})}^{2}}$

B) $\frac{2.5 y^{- 2}}{{(y_{1} + y_{2} - y_{3})}^{2}}$

C) $\frac{500}{y_{1} + y_{2} - y_{3}}$

D) $\frac{2.5 \times 10^{5} y^{2}}{{(y_{1} + y_{2} - y_{3})}^{2}}$

Show Answer

Answer:

Correct Answer: D

Solution:

[d] $Δ_{m}^{\infty} B a S O_{4} = 2 Δ_{e} q^{\infty} (B a S O_{4})$

$Δ_{e} q^{\infty} (B a S O_{4}) = Δ_{e} q^{\infty} (B a^{2 +}) + Δ_{e} q^{\infty} (S O_{4}^{- 2})$

$= Δ_{e} q^{\infty} (B a C l_{2}) + Δ_{e} q^{\infty} (H_{2} S O_{4}) - Δ_{e} q^{\infty} (H C l)$

$Δ_{e} q^{\infty} (B a S O_{4}) y_{1} + y_{2} - y_{3}$

$Δ_{m}^{\infty} = 2 (y_{1} + y_{2} - y_{3})$

For sparingly soluble salt, $Δ_{m}^{\infty} = \frac{k}{m} \times 100$

or $M = \frac{y}{2 (y_{1} + y_{2} - y_{3})} \times 1000$

$= \frac{500}{y_{1} + y_{2} - y_{3}}$

$K_{s p} = M^{2} = \frac{2.5 \times 10^{5} y^{2}}{{(y_{1} + y_{2} - y_{3})}^{2}}$
