Description

System

The blue bottle experiment is a model experiment to illustrate an organic redox system. The redox indicator methylene blue is oxidised by air to a colourless form. The air is fed into the solution using a pump. The glucose present in the solution reduces it back to its coloured form. This process is reversible and is automated in this experiment using a two-point control.

Themes

Get to know the organic redox reaction and the redox indicator methylene blue.
Carry out the Blue Bottle experiment in a new, automated version.
Setup and application of a two-point control system
Photometry with an immersion photometer
Use carbohydrates such as glucose as a reducing agent
