Which Substance When Dissolved in Water will Conduct an Electrical Current?
Safety: Do not ingest the substances used in this project
Some substances when dissolvedin water to produce a solution will conduct an electrical current. Such substances produce ions when dissolved in water, and it is the ions which carry the current through the solution. The research aspect of this science fair project is to use a conductivity device to determine if various substance dissolved in water can or cannot conduct electricity.
