The solution of NaOH in methyl orange indicator will turn from yellow to red. Methyl orange is an acid-base indicator that changes color in response to a change in pH. In the presence of a strong base like NaOH, the indicator will change to a red color indicating the basic nature of the solution.
The color of methyl orange is red. The color is red when the acetic acid is below pH 3.1.
A suitable indicator for an endpoint at pH 10.5 would be methyl orange. At this pH, methyl orange changes color from red to yellow, making it a good choice for acid-base titrations that end around pH 10.5.
Methyl 2-methylbutyrate can be prepared by the esterification of 2-methylbutyric acid with methanol in the presence of a strong acid catalyst, such as sulfuric acid. The reaction is usually carried out under reflux conditions and the ester is then isolated by extraction and distillation.
Methyl orange is also known as p-dimethylamino-azobenzenesulfonic ACID.As stated on wikipedia, hence I would have to say that it is in fact an acid, interestingly, it is an acid that tells us whether a substance is an acid or alkali, by changing colour.It is known as an INDICATOR.In:Acid=Red. Alkali=Yellow. Neutral=Orange, thus the name methyl orange.HAHA.There you go. A decent answer.Hope this helps.
When nitric acid reacts with methyl orange, the color of the solution changes. Methyl orange is an indicator that changes color from orange/yellow in acidic solutions to red in basic solutions. In the presence of nitric acid, which is a strong acid, the solution would turn red.
Methyl orange is a pH indicator that changes color in acidic and basic solutions. When added to sulfuric acid, which is a strong acid, the methyl orange changes color from yellow to red. This color change indicates that the solution is highly acidic.
To prepare methyl orange indicator for titration, dissolve 0.1g of methyl orange powder in 100mL of distilled water. This will give you a 0.1% solution of methyl orange which is suitable for use as an indicator in acid-base titrations.
This is so since the pH at the end point of Phenolphthalein is 9.1 and methyl orange is 3.7. For a strong acid strong base titration which the end point is between 3-11 phenolphthalein is used
Methyl orange is an acid-base indicator that changes color in the presence of acids and bases. In basic conditions, such as with a strong base like sodium hydroxide, methyl orange will turn yellow or orange.
Methyl Red
Methyl orange is used as an indicator in the determination of ZnO because it changes color from red to yellow at a pH range of 3.1-4.4, which is suitable for the titration of ZnO with a strong acid like hydrochloric acid. This color change helps in determining the endpoint of the titration accurately.
The equation of the titration using methyl orange as an indicator depends on the specific reaction being titrated. Methyl orange is typically used in acid-base titrations, where the indicator changes color in the presence of a certain pH range. For example, in a titration of a strong acid (e.g., HCl) with a strong base (e.g., NaOH), the equation would involve the stoichiometry of the acid-base reaction, with the color change of methyl orange indicating the endpoint of the titration.
For the titration of a strong acid, the indicator typically used is phenolphthalein. Phenolphthalein changes color in the pH range of 8.2 to 10, which is suitable for titrating a strong acid with a strong base to determine the equivalence point.
Acid Alkali Indicator Details Strong Strong Methyl Orange pipette alkali, and burette acid (change from yellow to light pink when neutralised) Weak Strong Phenolphthalien pipette acid, and burette alkali (change from colouless to salmon pink when neutralised) Strong Weak Methyl Orange pipette alkali, and burette acid (change from yellow to light pink when neutralised) Acid Alkali Indicator Details Strong Strong Methyl Orange pipette alkali, and burette acid (change from yellow to light pink when neutralised) Weak Strong Phenolphthalien pipette acid, and burette alkali (change from colouless to salmon pink when neutralised) Strong Weak Methyl Orange pipette alkali, and burette acid (change from yellow to light pink when neutralised)
Since the titration is between a strong acid and a weak base, methylorange should be suitable as the equivalence point is around pH 5. The K of the indicator should be equal to the pH at the end point. Methyl orange is that indicator
IN ACID: it turns methyl orange pink In base: it turns methyl orange yellow
