Hcl reaction to methyl orange

WebSep 22, 2024 · Why methyl orange is used in the titration of HCl vs Na2CO3? ... When we use something like phenolphthalein as the end-point indicator, the color change corresponds to the first reaction. Methyl orange, on the other hand, is the perfect indicator for this scenario as it will change color corresponding to the completion of the overall reaction. ... WebOct 28, 2024 · For this reaction to take place, the solution must be alkaline or slightly acidic. In our case, to obtain methyl orange, we start by diazotizing sulfanilic acid, dissolve dimethylaniline in dilute HCl, and finally mix both solutions so that the copulation reaction can take place.
