Consider the following statements regarding molar conductivity: Statement A: The value of constant ' A ' in the equation _m = _m^ - A c depends only on temperature and is independent of the type of electrolyte. Statement B: All electrolytes of a particular type (e.g., 1-1, 2-1) have the same value for ' A ' at a given temperature and solvent. Statement C: The limiting molar conductivity of weak electrolytes can be ob
Options
- AOne
- BTwo
- CThree
- DFour
Correct answer
B. Two
Step-by-step solution
Statement A is incorrect because the constant ' A ' depends on the type of electrolyte (i.e., the charges on the cation and anion produced on dissociation). Statement B is correct. All electrolytes of a particular type (like 1-1, 2-1) have the same value for ' A ' for a given solvent and temperature. Statement C is incorrect. For weak electrolytes, _m increases steeply on dilution, especially near lower concentrations. Therefore, _m^ cannot be obtained by extrapolation of the _m vs c plot to zero concentration. Sta
