Which statement is not correct for Kohlrausch law?
Correct answer: B. The law is valid for weak electrolytes only
- A. The law is valid at infinite dilution
- B. The law is valid for weak electrolytes only
- C. The basis of the law is independent migration of ions
- D. None of the above
Explanation
Kohlrausch's law states that the molar conductivity of an electrolyte at infinite dilution is the sum of the contributions of the individual ions. It is valid for both strong and weak electrolytes, contrary to the statement that it is valid only for weak electrolytes. Therefore, option B is incorrect, making it the correct choice for this question. Options A and C accurately describe aspects of Kohlrausch's law, and option D is incorrect because option B is the correct answer.

About Electrochemistry
Electrochemistry describes electron transfer through oxidation and reduction, identifies oxidizing and reducing agents, and applies oxidation numbers to balance redox equations. It also covers electrode potential and the standard hydrogen electrode, which provides the reference for comparing the reduction tendencies of other electrodes.
