Add some color to your chemical reactions while learning about the pH scale!Order Now
You’ll become a chemical artist in this experiment, making water change colors while observing the pH of the five substances that you create. Everything you need to conduct this experiment is found in your Creation Crate kit (besides the water). First, you’ll create a solution of thymol blue and water, which you’ll later add to five different substances. You’ll be able to make a rainbow of your own, noting how the solutions change color with the addition of the thymol blue and water mixture. The color of the final solution depends on their pH values. You’ll learn that pH is an important characteristic determined by the concentration of hydrogen and hydroxide ions in an aqueous solution. Start experimenting and reveal the rainbow.
What you'll receive in the Rainbow Liquid project kit:
Found in the Starter Kit:
Glass Beaker (150mL)
Double Ended Measuring Spoon
Sodium Hydrogen Carbonate
Sodium Hydrogen Sulfate
Continue the Chemistry Course, expanding your knowledge of important concepts that unlock a greater understanding of the world around you.
Acidic vs. Alkaline Substances. Learn what makes a substance basic or acidic and how to tell the difference.
The pH Scale & Indicators. Understand the scale that scientists use to measure how acidic or basic a substance is.
Predicting Chemical Reactions. Use your knowledge to be able to predict how substances interact with each other based on their characteristics.

Predicting Chemical Reactions
You may have heard of pH levels in the context of swimming pools or stomach acid. Maintaining the right level is super important—but why? Learn all about acids, alkalis, and the pH scale with the fascinating, colorful experiments in this lesson. Understand why some substances don’t affect the pH level of a solution at all, while others have a big influence. You’ll also use your knowledge and skills that you’ve learned throughout the course to be able to predict how chemicals will interact with each other.
