Question

Which statement is wrong about the variation of molar conductivity with dilution for a given electrolyte?

• A. Depends upon ionic mobility and degree of dissociation of all electrolytes
• B. Depends upon ionic mobility and degree of dissociation of weak electrolytes
• C. Depends upon ionic mobility for strong electrolytes
• D. Depends upon the nature of ion furnished by electrolytes on dissolution

Answer 1

The correct option is A Depends upon ionic mobility and degree of dissociation of all electrolytes

For strong electrolytes, the molar conductivity is independent of the degree of dissociation, as strong electrolytes are completely dissociated.
For weak electrolytes, the molar conductivity depends on the degree of dissociation.
Thus, the statement A is incorrect.
