RXMARINE CHEMICAL TAG::
Methyl orange has the property to color alkaline and neutral water yellow.Thus, phenol red is a bifunctional indicator with two transition pH ranges.
Indicator colors Methyl orange is a pH indicator frequently used in titration because of its clear and distinct color variance at different pH values.
Methyl Yellow used as a pH indicator. It is an acid-base indicator that changes color from below pH 2.9 red to above pH 4.0 yellow and vice versa.
Typical use is in the titration of a weak base with a strong acid.
