WebThe 'blue bottle' experiment An alkaline solution of glucose acts as a reducing agent and reduces added methylene blue from a blue to a colourless form. Shaking the solution raises the concentration of oxygen in the mixture and this oxidises the methylene blue back to its blue form. rick whaley \\u0026 the perdido brothershttp://www.actforlibraries.org/the-blue-bottle-experiment-explained/ rick whalleyWebIn this experiment, we will observe the diffusion of two dye molecules through agar gel. Methylene blue has a molecular weight of ~320, and potassium permanganate has a molecular weight of 158. The agar gel is a Jello-like substance, composed of ~98% water. Because of its high water content, the dye molecules will move freely through the gel. rick whaley \u0026 the perdido brothersWebE = milliequivalents of methylene blue per milliliter V = milliliters of methylene blue solution required for the titration, and W = grams of dry material 2.2.

The Potassium hydroxide (KOH) is an inorganic compound and "strong base" and used in this experiment as a nucleophile. As a nucleophile the KOH serves as a source of OH- to attack the polar bonds of the methylene blue. Methylene blue acts as a catalyst in this reaction. rick wheeler obituary - austin
