x y leftharpoons x2++y2- Lambda m ∞=57+73=130 Scm 2 mol -1

Q. Molar ionic conductivities of a two-bivalent electrolytes $x^{2 +}$ and $y^{2 -}$ are $57$ and $73$ respectively. The molar conductivity of the solution formed by them will be

$130 S c m^{2} m o l^{- 1}$

$65 S c m^{2} m o l^{- 1}$

$260 S c m^{2} m o l^{- 1}$

$187 S c m^{2} m o l^{- 1}$

$x y ⇌ x^{2 +} + y^{2 -} Λ_{m}^{\infty} = 57 + 73 = 130 S c m^{2} m o l^{- 1}$
