San Diego State University Strong and Weak Electrolytes Lab Report

Beyond Labz Strong and Weak Electrolytes

In this simulation you will prepare aqueous solutions of various compounds and measure their conductivity of electricity using a conductivity probe. You will identify electrolytes and non-electrolytes and relate the conductivity of the solutions to the composition of the compounds.

As a basis for understanding this lab you should read Chapter 3, section 3-4 Ions and Molecules in Aqueous Solutions page 105 – 107 of the Kotz 9th Ed text.

You can also watch this approx. 4 min video about strong and weak electrolytes.

Beyond Labz Instructions

Download the Beyond Labz worksheet for Strong and Weak Electrolytes. Print this worksheet so that you can follow the directions on what to do, fill it in and submit it. (Please use this worksheet from Canvas instead of looking in the Beyond Labz software.)

Now launch the Beyond Labz software, and open the Chemistry Lab.

To launch the simulation look at the list of worksheets on the bottom left of the window. Click “Reactions and Stoichiometry” and then select “Strong and Weak Electrolytes”. The lab will then open.

Follow the instructions in the worksheet. It is a good idea to read through the entire worksheet first before you begin so that you are aware of what is expected.

As you progress through the simulation, fill in data and observations on the worksheet in blue or black ink. No pencil! Even though this is a virtual lab this is good lab practice and also important to make sure your submitted work will be clear enough to grade.

To help you get started you can watch a short prelab demo of Beyond Labz that I made as a narrated powerpoint presentation or videoPlay media comment.

Preparing and submitting your work

After you complete the worksheet, take a picture of each completed page or scan them. Make sure the quality is good enough to view clearly. If I cannot read it, I will not grade it.

It is best to submit as a PDF or .jpeg (jpg) file. You can submit one file for each page of the table or combine them into one file.

It is best if you submit one file for each simulation.
