Clock Reaction Demonstration
Product Code : JA-DE-6738
The Clock Reaction Demonstration (SKU JA-DE-6738) is a modified iodine clock reaction: two colourless solutions are mixed and, after a short, predictable delay, the whole mixture suddenly turns dark blue. Running it again warmer or more concentrated shortens the delay, while diluting lengthens it, so the demonstration shows the factors that control reaction rate. This iodine clock reaction demonstration is supplied by JaincoLab for school and college chemistry lessons on kinetics.
Specifications
The demonstration is a modified iodine clock reaction in which two colourless solutions give a sudden dark-blue colour after a delay; repeating it at higher temperature or concentration shortens the delay and dilution lengthens it; reagents, quantities and the number of runs per kit are confirmed on the quotation.

Teaching reaction rates with the clock reaction
Because the colour appears suddenly after a measurable time, students can time the delay at different temperatures and concentrations and plot the results, which makes the clock reaction a standard introduction to rates of reaction and chemical kinetics.

Frequently asked questions
What happens in the clock reaction?
Two colourless solutions are mixed and, after a delay, the mixture suddenly turns dark blue.
How does it show reaction rate?
Raising temperature or concentration shortens the delay and dilution lengthens it.
How many runs does a kit give?
This is not stated in the product data and is confirmed on the quotation.
