The methylene blue value is defined as the number of milliliter's standard methylene value solution decolorized 0.1 g of activated carbon (dry basis). [65] Methylene blue value reflects the amount of clay minerals in aggregate samples. [ 66 ]
The aqueous solution in the classical reaction contains glucose, sodium hydroxide and methylene blue. [14] In the first step an acyloin of glucose is formed. The next step is a redox reaction of the acyloin with methylene blue in which the glucose is oxidized to diketone in alkaline solution [6] and methylene blue is reduced to colorless leucomethylene blue.

The blue part of this diagram of a propene molecule is a methylidene group. A methylidene group is any part of a molecule that consists of a CH 2 = group. [7] The group may be represented as =CH 2, where the '=' denotes the double bond. In contrast, methylene is connected to the rest of the molecule by two single bonds. [8]
New methylene blue (also NMB) [clarify] is an organic compound of the thiazine class of heterocycles. It is used as a stain and as an antimicrobial agent. It is classified as an azine dye, and the chromophore is a cation, the anion is often unspecified.

The observed spectrum (green) is the sum of the spectra of HA (gold) and of A − (blue), weighted for the concentration of the two species. When a single indicator is used, this method is limited to measurements in the pH range p K a ± 1, but this range can be extended by using mixtures of two or more indicators.
Methyl blue is a chemical compound with the molecular formula C 37 H 27 N 3 Na 2 O 9 S 3.It is used as a stain in histology, [1] and stains collagen blue in tissue sections. It can be used in some differential staining techniques such as Mallory's connective tissue stain and Gömöri trichrome stain, and can be used to mediate electron transfer in microbial fuel cells.
