Energy Stick

Energy Stick
Completely safe to touch and handle, simply complete the circuit by touching both electrodes at the end of the stick simultaneously.

Simple aparatus that allows you to test the conductivity of various solutions.  Constructed of two platinum electrodes connected to a non conductive support.  The light globe attached to each electrode will indicate the conductiveness of the tested solutions.

Note: Requires a 6-10V power supply or battery and connecting leads, battery jar and solutions (not included)

How It Works

This experiment tests whether a liquid or a solution is an electrolyte (conduct electricity) or a non-electrolyte. Electrolysis is brought about by the movement of ions. Ions must be present in solution for electrical conductivity. Salt, acid and alkali solutions containing ions are called electrolytes.

As the current flows, the ions move to the electrodes placed in the solution. If a light bulb in the circuit lights up, a current is flowing in the circuit. Electrolysis brings about chemical decomposition. Ions are attracted to the electrode with the opposite charge. Ions are discharged at the electrodes when the current flows, and new products are formed at the electrodes.
