The ionic conductance of Ba ²⁺ and Cl ⁻ are respectively 127 and 76 ohm ⁻¹- cm ^2 at infinite dilution. The equivalent conductance (inohm ⁻¹ ~cm ^2 ) of BaCl ₂ at infinite dilution will be

Step-by-step solution

Equivalence conductance = conducting power of all the ion produced by one gram equivalent of an electrolyte. Since, Eq. wt. of BaCl ₂= mol . wt. 2 then aligned _ BaCl ₂ ^ & = 1 2 ^ Ba ²⁺+ ^ Cl ⁻ & = 127 2 +76 & =139.5 ohm ⁻¹ ~cm ^2 aligned
