Chemical Properties:

Orange-yellow powder. Soluble in hotwater; insoluble in alcohol.


  1. Methyl Orange 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.
  2. Methyl orange has been used as pH control of chemical reactions and acid-base titration analysis of chemical products and intermediates in laboratory, industrial and agricultural production. In the printing and dyeing industry, the residual pH on the fabric should be measured and cleaned with an indicator to make the fabric neutral. If there is acidity on the cloth chemicalbook, its hair color and fastness will be affected when dyeing or printing with reactive dyes. The disadvantage of methyl orange indicator is that it is difficult to identify the yellow red color. Now it has been widely replaced by indicators. Methyl orange is also an azo dye, which can be used for printing and dyeing textiles.
  3. Methyl Orange As an acid-base indicator, pH 3.1 (red) – 4.4 (yellow), also used for biological staining.
  4. Methyl OrangeAcid be used as base indicator, pH value discoloration range is 3.1 (red) ~ 4.4 (yellow), and the alkalinity of most mineral acids, strong bases and water is measured; Volumetric determination of tin (SN2 + discolors methyl orange when hot); Achromatic indicators of strong reducing agents (Ti3 +, CR2 +) and strong oxidizing agents (chemicalbook chlorine, bromine); Spectrophotometric Determination of chlorine, bromine and bromine ions; It can be mixed with indigo sodium disulfonate or bromocresol green to shorten the color gamut and improve the sharpness of color change; Redox indicator, such as for titrating trivalent arsenic or antimony with potassium bromate
