Submit Previous Answers Request Answer Un input for part B ? X Incorrect; Try Again; 5 attempts remainingWhich of the following is/are TRUE about molar conductivity? The molar conductivity provides information about the current-carrying ability of the ions produced by one mole of the substance. For strong electrolytes, molar conductivity decreases slightly as the concentration is increased. At infinite dilution, each ion derived from the electrolytes makes a definite contribution to the molar conductivity. Debye-Hückel Theory states that the molar conductivity of an electrolyte at infinite dilution is the sum of the molar conductivity of its constituent ions. II, IV I, II, IV I, III, IV I, II, IIITrue or False For strong electrolytes, such as hydrochloric acid, the molar conductivity decreases slightly as the concentration is increased.
