Type: MCQ-numerical-Medium-Class 12
At infinite dilution equivalent conductances of Ba²⁺ & Cl⁻ ions are 127 & 76ohm⁻¹cm² eq⁻¹ respectively. Equivalent conductance of BaCl₂ at infinite dilutions is :
A
139.5
B
101.5
C
203
D
279
Correct Answer
Option A
Detailed Explanation
The equivalent conductance of BaCl₂ is the sum of the conductances of Ba²⁺ and 2Cl⁻ ions: 127 + 2×76 = 279.
