Vitamin C Clock Reaction - Effect of Concentration on Reaction Rate - Student Laboratory Kit

By: The Flinn Staff


Your students won't be “watching the clock” during this class period! They will be jumping at the chance to perform their very own clock reaction experiment using common chemicals. Students mix two colorless solutions of varying concentrations together and watch in amazement as the mixed solution suddenly flashes to blue. How long will it take for the clock to “ring”? Students discover that it depends on the concentration of the reactants! This activity provides a simple yet dramatic way to introduce the topic of reaction rates and to explore factors that affect the rate.

Includes complete instructions with reproducible student handouts, valuable Teacher Notes, and all the necessary chemicals for the experiment and the recommended disposal procedure.

Complete for 30 students working in pairs. Super Value Kit is complete for 5 classes of 30 students working in pairs.
