Today I'm having fun with acids and bases as I experiment with color changing indicators! This is bromothymol blue, an indicator used to detect weak acids. We used it in climate camp to test for evidence of ocean acidification, we'll be using it in chemistry camp to test for carbon dioxide when we exhale! All kids have to do is blow bubbles to spark a chemical reaction color change! ❤️ | The Scientific Mom

Dry ice bromothymol blue Litmus solution Universal Indicator Soap The solutions begin to bubble, the white mist rises and the indicators change their color. The -78 ° C cold, solid dry ice evaporates in much warmer water. Dry ice has the property of passing directly into the gaseous aggregate state. Large amounts of carbon dioxide dissolve in water. With a corresponding saturation, a small part thereof reacts in the following manner: H2O CO 2 H 2 CO 3 | ChemClub
