Why is Graphite used to make electrodes?

Open in App

Solution

Graphite can conduct electricity due to the vast electron delocalization within the carbon layers (a phenomenon called aromaticity). These valence electrons are free to move, so are able to conduct electricity, therefore, graphite is used to make electrodes.
