The electrical conductivity of an electrolytic cell depends on various factors, including:

i. Concentration of electrolyte: The conductivity of an electrolytic solution generally increases with an increase in the concentration of the electrolyte. This is because a higher concentration of ions allows for more charge carriers, leading to increased conductivity.

ii. Amount of electrolyte added: Similar to concentration, adding more electrolyte to a solution increases the number of ions present and therefore increases the conductivity.

iii. Temperature: Generally, the conductivity of electrolytic solutions increases with an increase in temperature. This is because higher temperatures lead to increased ion mobility, allowing ions to move more freely and increasing conductivity.

iv. Nature of electrode: The nature of the electrode can affect the conductivity of an electrolytic cell to some extent. For example, certain electrode materials may have a higher resistance, which can affect the overall conductivity of the cell.

Out of the given options, the electrical conductivity of an electrolytic cell does not depend on the nature of the electrode (iv). While the nature of the electrode may have some influence, it is not a primary factor affecting conductivity compared to the other factors listed.

Therefore, the correct answer is (iv) Nature of electrode.
