Classroom Resources: Solutions

1 – 2 of 2 Classroom Resources

• 

  Conductivity | High School

  Lab: Strong and Weak Electrolytes

  In this lab, students will analyze the conductivity of several common household solutions using a light emitting conductivity diode tester to determine if the solution is a strong or weak electrolyte. Students will interpret the brightness of the lightbulb to determine the strength of the electrolyte. Students will also have an opportunity to consider the connection between conductivity and bond type during this lab.

  Classification of Reactions, Conductivity, Chemical Change, Precipitate | High School

  Demonstration: Sterno

  In this demonstration, students will observe a decomposition reaction that triggers a precipitate reaction that prevents a solution from conducting electricity.
