Methyl orange is an intensely colored compound used in dyeing and printing textiles. It is also known as C. I. Acid Orange 52, C. I. 13025, helianthine B, Orange III, Gold orange, and Tropaeolin D. Chemists use methyl orange as an indicator in the titration of weak bases with strong acids. It changes from red(at pH 3. 1) to orange-yellow(at pH 4. 4).... Methyl orange is synthesized by reaction of sulfanilic acid, sodium nitrite, and dimethylaniline.  8, record 4, English, - methyl%20orange

Methyl Red Voges Proskauer Test(MR-VP)-differentiates members of family Enterobacteriaciae based on ability to produce acid end products from fermentation of glucose. Enterobacteriaciae divided into two groups based on type of formic acid fermentation performed. 1.) Mixed acid type formic acid fermentation-results in production of ethanol and lactic, acetic, succinic, and formic acids as fermentation end products. If mixed acid fermentor, then when Methyl Red added to inoculated broth, medium turns red. If butanediol fermentor, then the color of the medium will change to yellow. Butanediol fermentor yields orange/yellow color after addition methyl red. 2.) Butanediol fermentors produce acidic fermentation products.  5, record 7, English, - mixed%20acid%20fermentation
