Blue bottle experiment. 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 ...
Methylene blue is a monoamine oxidase inhibitor (MAOI), [50] and if infused intravenously at doses exceeding 5 mg/kg, may precipitate serious serotonin toxicity, serotonin syndrome, if combined with any selective serotonin reuptake inhibitors (SSRIs) or other serotonin reuptake inhibitor (e.g., duloxetine, sibutramine, venlafaxine, clomipramine ...
Iodine clock reaction. The iodine clock reaction is a classical chemical clock demonstration experiment to display chemical kinetics in action; it was discovered by Hans Heinrich Landolt in 1886. [ 1] The iodine clock reaction exists in several variations, which each involve iodine species ( iodide ion, free iodine, or iodate ion) and redox ...
The Tyndall effect is light scattering by particles in a colloid such as a very fine suspension (a sol ). Also known as Tyndall scattering, it is similar to Rayleigh scattering, in that the intensity of the scattered light is inversely proportional to the fourth power of the wavelength, so blue light is scattered much more strongly than red light.
Also, experiments indicate that the ratios of deuterium fusion remain constant at different energies. [146] In general, pressure and chemical environment cause only small changes to fusion ratios. [146] An early explanation invoked the Oppenheimer–Phillips process at low energies, but its magnitude was too small to explain the altered ratios ...
Brilliant blue FCF is a synthetic dye produced by the condensation of 2-formylbenzenesulfonic acid and the appropriate aniline followed by oxidation. [ 4] It can be combined with tartrazine (E102) to produce various shades of green. It is usually a disodium salt. The diammonium salt has CAS number 2650-18-2.
