Electrical Conductivity Lab - Exp 13 Part A - Test the conductivity of substances

In this video we look at the electrical conductivity of many difference substances by checking to see if an electrical current can flow through it and light up a light bulb.

Remember that electrolytes have ions in the solution, and are thus able to have electricity flow through it. To simplify: strong electrolytes have a lot of ions, so the lightbulb should light up and be very bright. Weak electrolytes have few ions, so the lightbulb should light up but be dim. Nonelectrolytes have no ions, so the lightbulb should not light up.

Make your observations!
