A Sample Lab Report The Iodine Clock Reaction Introduction

WebIodine Clock Reaction. Clock reactions are so called because they show a sharp dramatic colour change after a period of time has elapsed. They make ideal reactions for studying kinetics. Iodine clock reactions come in a number of variations, but they generally all use starch to show a sudden purple-black colour at the end of the reaction.

Iodine is very weakly soluble in the water, and can be easily lost from the solution due to its volatility. However, in the presence of excess iodides iodine creates I 3- ions. This lowers free iodine concentration and such solutions are stable enough to be used in lab practice.
