How is saltwater able to conduct electric charge between two wires?
Say I put some wires in a container filled with saltwater, but the wires do not touch, and I connect these wires to a battery:
simulate this circuit – Schematic created using CircuitLab
I know that the saltwater will complete the circuit, and some current will flow. But how can this happen? Do the electrons fly off one wire and jump through the saltwater to the other wire? Aren't the electrons stuck in the wire? Why would they be able to do this when there is saltwater between the wires, but not when there is air between the wires? If the electrons can't leave one wire, travel through the saltwater, and get to the other wire (can they?), then how is there a complete circuit?
