Quick answer: Blue Bottle Kit is a chemistry teaching kit manufactured by Ambala Science Lab in Ambala, Haryana, India, and supplied to schools, colleges, nursing and medical teaching institutions in India and export markets.
Learning Objectives : Develop and use a model to represent what happens in the blue bottle reaction. Illustrate and explain the reaction on a molecular level. Write equations representing the 2 phases of the reaction. Students observe that shaking a capped, half-filled bottle of a clear solution causes the solution to turn blue immediately. Upon standing, the blue color fades to colorless. The color can be regenerated numerous times by shaking the bottle and contents. Given that the bottle has dissolved solutes of glucose, potassium hydroxide, and a redox indicator (methylene blue), students apply their prior knowledge of chemical reactions to develop a model for what is happening at a molecular level. They use evidence to support the claim that oxygen in the air above the solution must be present to initiate the reaction. Shaking the bottle causes gaseous oxygen to dissolve in solution. Then, aqueous oxygen oxidizes colorless methylene blue to its blue oxidized state. Further evidence that oxygen is necessary is that after numerous cycles, it takes longer periods of shaking to turn the solution blue due to less oxygen being available in the air above the solution.
