Molar conductances of BaCl2, H2SO4 and HCl at infinite dilutions are x1, x2 and x3, respectively. Equivalent conductance of BaSO4 at infinite dilution will be :

A

x1+x2−x32\frac{x_{1} + x_{2} - x_{3}}{2}

B

x1−x2−x32\frac{x_{1} - x_{2} - x_{3}}{2}

C

2(x1+x2−x3)\left( x_{1} + x_{2} - x_{3} \right)

D

[x1+x2−x3]2\frac{\left\lbrack x_{1} + x_{2} - x_{3} \right\rbrack}{2}

Answer

[x1+x2−x3]2\frac{\left\lbrack x_{1} + x_{2} - x_{3} \right\rbrack}{2}

Explanation

Solution

∧m,BaSO4\wedge _ { \mathrm { m } , \mathrm { BaSO } _ { 4 } }= (x1 + x2 x – 2x3)⇒\Rightarrow

= ∧eq. ,BaSO4n− factor \frac { \wedge _ { \text {eq. } } , \mathrm { BaSO } _ { 4 } } { \mathrm { n } - \text { factor } }

=(x1+x2−2x3)2\frac { \left( x _ { 1 } + x _ { 2 } - 2 x _ { 3 } \right) } { 2 }
