where Doxis the oxidised (blue) form of methylene blue and CH is the carbohydrate, glucose. A simple mechanism for the reaction is: Hyoscyamine/­hexamethylenetetramine/­phenylsalicylate/­methyleneblue/­benzoicacid (trade names Methylphen, Prosed DS) is a drug combination. It is not safe or effective for any medical purpose. [12] While chemiluminescence can be a great way to show that chemical reactions can release energy as light, rather than heat, photochemical reactions provide opportunities to show the complementary process. The blueprint, or cyanotype, reaction is one of the most famous and lasting demonstrations of this phenomenon. It provides a visually stimulating and memorable activity with a lot of room for creative development.

What is an oxidation–reduction reaction?

The mixture painted onto the paper, first used by John Herschel in 1842, contains potassium hexacyanoferrate(III) (ferricyanide) and ammonium iron(III) citrate. Isobutyl nitrite is known to cause methemoglobinemia. [26] Severe methemoglobinemia may be treated with methylene blue.
