liquid mercury

[Naji Sarsam 1F]

I was studying electrochemistry and saw that for a galvanic cell, liquid mercury can act as an electrode. How is this possible?

[Maggie Eberhardt - 2H]

it is part of a reference electrode known as a calomel electrode (Hg2Cl2). basically, using liquid mercury as an electrode takes advantage of its redox reactions

Is it required to know these different electrodes and what their functions could be for any sort of conceptual questions or solving problems in general.

I don't believe we will need to know the specifics about liquid mercury as an electrode for the final, as it is a more complex case and he said the test would be pretty straightforward.
