AI Image Prompt:
A molecular depiction of methyl orange, which is a pH indicator. It changes its color from red to yellow-orange within a specific pH range that spans from 3.1 to 4.4. This color change happens due to the presence of an azo group (-N=N-) coupled with two substituted aromatic rings, which are characteristics of azo dyes. Methyl orange is an azo dye with a molecular formula of C14H14N3NaO3S and a molecular weight of 327.34 g/mol. Its chemical structure enables it to function as a pH indicator, its color transitioning in response to changes in the acidity or alkalinity of the environment it’s in, making it useful in various applications such as determination of sludge alkalinity in oil procedures.
