Methyl orange decolorizationDecolorization of methyl orange (MO) by MnO2 was investigated with and without small molecules of organic acids such as formic acid. It was found that the decolorization could be significantly improved by MnO(2 )with the assistance of organic acids. The effect of ...
1. (Colours) any of a group of colours, such as that of a ripe tomato or fresh blood, that lie at one end of the visible spectrum, next to orange, and are perceived by the eye when light in the approximate wavelength range 740–620 nanometres falls on the retina. Red is the compl...
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 ...
Orange-yellow powder. Soluble in hotwater; insoluble in alcohol. Uses As indicator in 0.1% aqueous solution. pH: 3.1 red, 4.4 yellow. Employed for titrating most mineral acids, strong bases, estimating alkalinity of waters; useless for organic acids. In dyeing and printing of textiles. ...
which stabilize the new intercalated structure. Treatment of cells with this type of mutagen increases the frequency of occurrence of frameshift mutations. Examples of such mutagens include acridine orange, acriflavine, and ethidium bromide. These molecules are highly fluorescent and are commonly used ...
