Question

The equivalent conductance of $B{a}^{2+}$ and $C{l}^{-}$ are respectively $127$ and $76$ $oh{m}^{-1}$ $c{m}^{2}equi{v}^{-1}$ at infinite dilution. The equivalent conductance (in $oh{m}^{-1}c{m}^{2}equi{v}^{-\left(A\right)}$ of $BaC{l}_2$ at infinite dilution will be :

• A. $139.5$
• B. $203$
• C. $279$
• D. $101.5$

Answer 1

The correct option is A $139.5$

Equivalent conductance of $BaC{l}_2=\frac{127+26\left(2\right)}{2}$
$=139\cdot 5$
