Methyl Orange is an acid-base indicator. In dilute solution, at a pH greater than 4.4, it is yellow. At pH=3.2, the solution appears red. Draw a structure of the species that is formed at the lower pH of the acid proton that adds to the azo nitrogen atom adjacent to the aromatic ring containing the -SO3 group. Why does the proton add to this particular nitrogen when two other nitrogen atoms are available in the molecule?© BrainMass Inc. brainmass.com October 9, 2019, 3:43 pm ad1c9bdddf
The reason why the H adds to that particular nitrogen is because ...
This solution contains the two possible structures which this chemical compound can form at a lower pH, as well as an explanation as to why hydrogen and nitrogen bond in the manner that they do. A word document attachment accompanies this solution and presents the chemical structures needed for the answer.
