Use
Methyl orange is an orange, azoic dye. It has a transition range from 3.1 to 4.4. Methyl orange does not have a full spectrum of color change, but has a sharper end point. Methyl orange shows red color in acidic medium (pH 3.1) and yellow color in basic medium (pH 4.4). It is used as a pH-indicator in 0.1% aqueous solution for the titration of mineral acids (not organic acids) and strong bases. Methyl orange is also used in dyeing and printing textiles as a dyestuff.
