About Litmus Test for Carboxylic Acids Virtual Lab Simulation

Did you know that carboxylic acids are found commonly in nature? In this simulation, you will learn how to perform the litmus test and how to interpret the test’s results. To do this, you will test six organic compounds that are from natural sources, and determine which of the natural sources contain carboxylic acids. 

 

Discover pH indicators

To determine which organic compounds are carboxylic acids, you will test each compound’s acidity using colourful pH indicators. With the help of a lab poster, you will discover the variety of naturally occurring pH indicators, such as Litmus, and find out how they work. Apply what you discovered, to learn what the results of the litmus test look like when dipping litmus paper in acidic, basic, and neutral solutions. 

 

Perform the litmus test

Now you are ready to perform the litmus test on the organic compounds. Begin by deducing which coloured litmus paper you should use to test for acids: red or blue? Then, learn the steps of the litmus test with helpful guidance from Dr. One. Once you are familiar with the steps, repeat the test for the remaining organic compounds. Do not worry if you make a mistake, as you can always restart the experiment by pressing the reset button.

 

Identify the carboxylic acids

After testing the compounds, there is one step remaining, and that is to interpret the results! Look at the results in front of you to determine which of the natural sources contains a carboxylic acid. Does spinach really contain carboxylic acids?
