Question

why does current flow in an electrolyte

Answer 1

In electric circuits this charge is often carried by moving electrons in a wire. It can also be carried by ions in an electrolyte, or by both ions and electrons such as in an ionised gas (plasma). ... These conduction electrons are the charge carriers in metal conductors.
