The ionic conductance of Ba ²⁺ and Cl ⁻ respectively are 127 and 76 ⁻¹ ~cm ² at infinite dilution. The equivalent conductance of BaCl ₂ , at infinite dilution will be
Options
- A330 ⁻¹ ~cm ²
- B203 ⁻¹ ~cm ²
- C139 ⁻¹ ~cm ²
- D51 ⁻¹ ~cm ²
Correct answer
C. 139 ⁻¹ ~cm ²
Step-by-step solution
aligned & _ m ^ for BaCl ₂= _ m ^ Ba ²⁺+ _ m ^ Cl ⁻ &= 1 2 127+76=139.5 ⁻¹ ~cm ² aligned
