is a slow reaction. Give four examples of a very fast reaction. A few reactions produce a colour change, for example due to the production of iodine. A colorimeter measures colour change.

The time period chosen may depend upon the rate of the reaction. For example, it may be a few seconds for a fast reaction or a few minutes for a slow reaction.
