Which allow electric current to pass through them, are good conductors of electricity.
Which do not allow electric current to pass through them easily, are poor conductors of electricity.
Most liquids that conduct electricity are solutions of acids, bases and salts.
Two wires are called leads.
Distilled water is free of salts and is a poor conductor.
When salt is dissolved in distilled water, we obtain salt solution. This is a conductor of electricity.
Oxygen bubbles formed on the electrode connected to the positive terminal of the battery and hydrogen bubbles formed on the other electrode.
