Web18 aug. 2024 · In the traditional blue bottle reaction, methylene blue in its oxidized, blue-colored form (MB +) reacts with glucose in the presence of base. This generates reduced methylene blue (MBH), which is colorless: 2,3,5 MB+ (blue colored) + glucose à MBH (colorless) + colorless products Web1 nov. 2024 · Why is sodium hydroxide used in the blue bottle experiment? The sodium hydroxide converts gluconic acid into sodium gluconate. Methylene blue acts as an indicator, but also speeds the reaction by serving as an oxygen transfer agent. As it oxidizes glucose, methylene blue is reduced to form colorless leucomethylene blue.
