Traffic Light Reaction Demo Lab
Product Code : JA-DE-6739
The Traffic Light Reaction Demo Lab (SKU JA-DE-6739) is a redox demonstration with a memorable colour sequence: a flask of pale yellow liquid turns red when it is gently swirled and then green when it is shaken harder, and the colours return as it stands. Teachers use it to open discussion of the oxidation and reduction steps behind each change. This traffic light reaction demonstration comes with instructions and is supplied by JaincoLab for school and college chemistry.
Specifications
The demonstration shows a colour sequence of pale yellow to red to green in a flask as it is swirled and shaken, and is supplied with instructions; the reagents in the kit, their quantities and the number of demonstrations per kit are confirmed on the quotation.

Teaching redox with the traffic light reaction
Shaking the flask mixes oxygen from the air into the solution, which oxidises the indicator through its red and green forms, while standing lets the reducing agent bring it back to yellow; the reversible sequence is used to explain oxidation, reduction and reaction rates.
- Introducing oxidation and reduction in secondary chemistry
- Showing the effect of dissolved oxygen on a reaction
- Discussing reversible colour changes and indicators
- Science clubs, open days and exhibitions
