Our explanation Salt water is made up of 7°A
sodium chloride and water. When salt is
added to water, the sodium and chloride
ions float freely in the water. Since an ion
has an electrical charge, it can carry
electricity through water. If a circuit is Made by: Mariana Mtz Covarrubias
created with an electricity source and a #19 7°A
light bulb, it is possible to light the bulb
using the salt water as a conductor.
