NEET Chemistry (general) MCQ Question
Type: MCQ-conceptual-Easy-Class 12
Which of the following statements about molar conductivity and ionic mobility are correct?
A
Molar conductivity increases with dilution for weak electrolytes.
B
Molar conductivity is independent of the type of ions present.
C
The limiting molar conductivity of an electrolyte is the sum of the contributions of its ions.
D
Ionic mobility decreases with increasing concentration of the electrolyte.
Correct Answer
Option A
Detailed Explanation
Molar conductivity does indeed increase with dilution for weak electrolytes, while the limiting molar conductivity is the sum of the contributions of individual ions, as stated in the NCERT context. However, ionic mobility is not independent of the type of ions and typically increases with dilution rather than decreasing.
