Objectives
- Students will observe whether different solutions conduct electricity.
- Students will relate this information to the concept of electrolytes and nonelectrolytes.
- Student will make predictions as to whether a solution will conduct electricity well, poorly, or not at all.
- Students will use solubility rules to predict the conductivity of ionic compounds.
Vocabulary
- anions
- cations

- solubility
- strong electrolyte
- weak electrolyte
About the Lesson
This lesson shows on the macroscopic level what occurs on the microscopic level when electrodes and a source of DC electricity are placed in a solution.
As a result, students will:
- Observe the particles in the solution when a source of current is added.
- Identify electrolytes and nonelectrolytes.
- Predict whether substances will conduct electricity well, poorly, or not at all.
