NEET Chemistry (general) MCQ Question
Which of the following statements about the molar conductivity of strong and weak electrolytes is correct?
For strong electrolytes, molar conductivity increases slowly with dilution and can be plotted as a straight line with L ° m as the intercept.
Weak electrolytes exhibit a linear increase in molar conductivity with concentration, similar to strong electrolytes.
The constant 'A' in the equation for strong electrolytes is independent of the type of electrolyte and the solvent used.
Molar conductivity for weak electrolytes can be calculated using the limiting molar conductivity of the individual ions according to Kohlrausch's law.
Correct Answer
Detailed Explanation
Statement A is correct as it reflects the behavior of strong electrolytes where molar conductivity increases slowly with dilution and can be graphically represented. Statement B is incorrect as weak electrolytes do not exhibit linear behavior. Statement C is false as 'A' varies with the electrolyte type. Statement D is partially true but does not specifically address the behavior of weak electrolytes in the context of the question.
