Solution

The correct option is B
False

Although it seems that electrolytic refining involves lower temperatures, this is not true. For instance, Crude Aluminum is refined using electrolysis which involves high temperatures to melt the electrolyte (Cryolite + $C a F_{2}$ saturated with $A l_{2} O_{3}$ ). Also, the extraction of Aluminum from $A l_{2} O_{3}$ is in itself a high-temperature process (happens between $950 - 1050^{\circ} C$ )

In both these cases, the medium is non-aqueous; meaning, the medium is not water.
