Blue bottle reaction video. The blue bottle experiment is a color-changing redox chemical reaction. An aqueous solution containing glucose, sodium hydroxide, methylene blue is prepared in a closed bottle containing some air. Upon standing, it spontaneously turns from blue to colorless due to reduction of methylene blue by the alkaline glucose ...

Brilliant blue FCF dye within beverages items—such as soda—can be used in the blue bottle experiment. In such foods, both the dye and reducing agents are incorporated in the same solution. When the solution is blue, oxygen is present. On the addition of NaOH, a reaction occurs that removes the oxygen, turning the solution clear.
[48] [46] The redox properties can be seen in a classical demonstration of chemical kinetics in general chemistry, the "blue bottle" experiment. Typically, a solution is made of glucose (dextrose), methylene blue, and sodium hydroxide. Upon shaking the bottle, oxygen oxidizes methylene blue, and the solution turns blue. The dextrose will ...
