What is the colour change of methyl orange? - Studybuff

WebReaction: When methyl orange is added to the base solution, the colour changes to yellow. The methyl orange changes colour at the pKa of a mid-strength acid. The colour is yellow because the acid nature of the solution gets decreased as it is a base, so the orange colour changes to fade to yellow. Suggest Corrections. 1. WebMethyl orange. Methyl orange is a synthetic indicator. The color of methyl orange in a basic solution is yellow. The color of methyl orange is red in an acidic medium. Structure of methyl orange. Hence, the color of methyl orange in the basic solution is yellow. WebCorrect option is A) Methyl orange acts as an indicator which changes its colour to indicate whether a medium is acidic or basic. As the acidity of the solution decreases, the intensity of the red colour also decreases, changing from red to orange and from orange to yellow with the increase in the pH and decrease in the acidity.
