Among the following statements related to ionic conductance, choose the correct statements.
A. Ionic conductance depends on the nature of the electrolyte
B. Ionic conductance is due to the movements of electrons
C. Ionic conductance is also called electronic conductance
D. Ionic conductance depends on temperature
E. Ionic conductance also depends on the nature of the solvent
Choose the correct answer from the options given below:
Answer & explanation
Correct answer: option 4
The correct answer is Option (4) → A, D, and E only
In electrolytic (ionic) conductance the current is carried by the movement of ions in the solution, not by electrons.
(A) Ionic conductance depends on the nature of the electrolyte — True. A strong electrolyte gives more ions than a weak one.
(B) Ionic conductance is due to the movements of electrons — False. It is due to the movement of ions; conduction by electrons is electronic (metallic) conductance.
(C) Ionic conductance is also called electronic conductance — False. Ionic conductance is called electrolytic conductance; electronic conductance is the conduction of metals.
(D) Ionic conductance depends on temperature — True. It increases as the temperature rises.
(E) Ionic conductance also depends on the nature of the solvent — True. The solvent and its viscosity control how freely the ions move.
