What is the factor responsible for the conductance of Electrolytic conductors?

Due to movement of ions towards oppositely charged electrodes.

The correct answer is option 2. Due to movement of ions towards oppositely charged electrodes.

Electrolytic conductors, also known as electrolytes, are substances that conduct electricity through the movement of ions in solution. Here is an detailed how this process works:

Dissociation in Solution:

When an electrolyte (such as a salt, acid, or base) dissolves in water, it dissociates into its constituent ions. For example, when sodium chloride (\(NaCl\)) dissolves in water, it dissociates into sodium ions (\(Na^+\)) and chloride ions (\(Cl^-\)).

Formation of Ions:

The dissolved ions are free to move throughout the solution. These ions carry electrical charges—positive for cations and negative for anions.

Application of Electric Field: When an electric field is applied across the solution (e.g., by connecting a battery to electrodes immersed in the electrolyte), the ions experience a force due to the electric field. This force causes the ions to move: cations are attracted to the cathode (negative electrode) and anions are attracted to the anode (positive electrode).

Movement of Ions:

The movement of ions constitutes an electric current. As the ions move towards the oppositely charged electrodes, they carry charge through the solution, allowing electrical conductivity.

Conductance Mechanism:

The overall conductance of the electrolytic solution is due to the mobility of these ions. The faster the ions can move, the higher the conductance of the solution. Factors such as ion concentration, temperature, and the nature of the electrolyte affect the mobility of ions and thus the conductance of the solution.

Comparison with Metallic Conductors:

In metallic conductors, electrical conductance is due to the movement of electrons. However, in electrolytic conductors, it is the movement of ions that is responsible for conductance.

In summary, the conductance of electrolytic conductors is primarily due to the movement of ions towards the oppositely charged electrodes when an electric field is applied. This ion movement allows the solution to conduct electricity.

Therefore, the correct answer is: Due to movement of ions towards oppositely charged electrodes.
