Question

Effect of distance between electrodes in electrolysis

Answer 1

You may expect no effect. The step controlling the electrolysis rate (i.e., the step with the lowest rate) is the diffusion of the electroactive species in the layers near the electrodes (diffusion layers).

The resistance of the solution is commonly very low (i.e., the ionic conductance of the solution is relatively high) and the solution is also stirred.

Answer 2

$\large { \fcolorbox{gray}{black}{ ✔\: \textbf{Verified \: answer}}}$

Electrolytes are salts or molecules that ionize completely in solution. As a result, electrolyte solutions readily conduct electricity.

Non-electrolytes do not dissociate into ions in solution; nonelectrolyte solutions do not, therefore, conduct electricity.
