What causes the color change of methyl orange?
The color changes that occur in methyl orange are due to changes in the electrons associated with the attachment or detachment of hydrogen ions. Normally, the methyl orange molecule absorbs blue-green light. This causes solutions of methyl orange to appear red.
What happens when methyl orange is added to neutral?
Note:Methyl orange shows different colours in acid, base and neutral substance. It changes colour from red to orange to yellow as the pH of the solution increases.
Why is methyl orange used as an indicator?
Methyl orange is a pH indicator frequently used in titrations because of its clear and distinct colour change. Because it changes colour at the pH of a midstrength acid, it is usually used in titrations for acids. Methyl orange shows red colour in acidic medium and yellow colour in basic medium.
What is the effect of acid on methyl orange?
Methyl orange has the property to color alkaline and neutral water yellow. If the water becomes acidic, it turns red immediately.
What happens when a methyl orange solution is mixed with HCL?
When methyl orange is added to dilute hydrochloric acid, the color of the solution gets converted into red.
Is methyl orange a weak acid or base?
Methyl Orange is a weak acid which dissociates in water forming orange neutral molecules. Under acidic conditions, the equilibrium is to the left, and the concentration of the neutral molecules is too low for the orange colour to be observed.
What happens when methyl orange solution is mixed with HCL?
When methyl orange is added to dilute hydrochloric acid, the color of the solution gets converted into red. Methyl orange is one of the widely used pH indicators, which is used in the titration. When methyl orange is used as an indicator with acid, the color of the solution turns red.
Why is methyl orange used instead of phenolphthalein?
If you use phenolphthalein, you would titrate until it just becomes colourless (at pH 8.3) because that is as close as you can get to the equivalence point. On the other hand, using methyl orange, you would titrate until there is the very first trace of orange in the solution….

Why phenolphthalein is used instead of methyl orange?
Is methyl orange good for weak acid strong base titration?
If a chemical indicator is used—methyl orange would be a good choice in this case—it changes from its basic to its acidic color. Titration of a weak base with a strong acid: A depiction of the pH change during a titration of HCl solution into an ammonia solution.
