How To Demonstrate an Effervescent Universal Indicator ‘Rainbow’ | LaBLiFe

In this short video, Emma Dent demonstrates how to create an effervescent universal indicator rainbow using hydrochloric acid and sodium carbonate, providing a vivid and engaging example of pH changes and acid-base reactions.
This experiment showcases the dynamic colour changes that occur as the pH shifts from acidic to basic and offers students valuable insight into chemical reactions and the properties of acids and bases.
By observing the effervescence and the resulting colourful spectrum, students gain a deeper understanding of how different substances interact at the molecular level, making this an exciting and educational learning opportunity in chemistry.
