Because it changes colour at the pH of a mid-strength acid, it is usually used in titrations for acids. Unlike a universal indicator, methyl orange does not have a full spectrum of colour change, but has a sharper end point. Indicator colours Methyl orange (pH indicator) below pH 3.1 ...
Methyl orange is a pH indicator frequently used in titrations, also used for histological microscopy. Definition An acid–base indicator that is red in solutions below a pH of 3 and yellow above a pH of 4.4. As the transition range is clearly on the acid side, methyl orange is suitable ...

Parathion-methyl mainly produces dimethyl thiophosphoric acid and p-nitrophenol, and a small part of p-nitrophenol is further metabolized by producing 4-nitrocatechol and 1,2,4-phloroglucinol (Geng et al., 2014). But some of the OPPs may be converted into more toxic products after entering the...
Sucrose, meat extract and peptone increased methyl orange decolourisation by freely suspended cells, whereas sodium acetate exerted a negative effect on decolourisation. In addition, it was observed that the yeast and meat extracts enhanced the degradation of the dye by the growing cells. Sucrose...
Re: Phenolphthalein vs Methyl orange «Reply #2 on:June 13, 2006, 08:49:24 PM » It is all about the colour change at what range of pH. eg. titrating NaOH with HCl. Since both are strong acid/base, then the pH of neutralisation is 7. This means the indicator I use should exh...

Genes are colour coded as follows: green = large subunit; blue = small subunit; yellow = putative hydrogenase maturation protease; orange = accessory proteins; red = b-type cytochrome subunit; purple = putative expression/formation protein; grey = nickel transporter; dark blue = nickel insertion...
A new Fe-based metallic glass with composition Fe76B12Si9Y3 (at. %) is found to have extraordinary degradation efficiency towards methyl orange (MO, C14H14N3SO3) in strong acidic and near neutral environments compared to crystalline zero-valent iron (ZVI) powders and other Fe-based metallic ...
