We can buy methyl orange(indicator) from scientific stores or chemical stores.
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.

Milk of magnesia is a basic solution. Therefore, methyl orange shows a yellowish orange colour. Further, this indicator shows a red colour in acidic solutions.
Methyl Orange is red in an acidic solution.
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.
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.
Methyl orange is a pH indicator having the chemical formula C14H14N3NaO3S.
To prepare screened methyl orange indicator, dissolve 0.05g of methyl orange powder in 100 mL of distilled water. Filter the solution through a filter paper to remove any particles. The resulting solution is ready for use as a screened methyl orange indicator.
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.
Alkalis turn methyl orange indicator yellow because the color of methyl orange changes depending on the pH of the solution. In acidic conditions, methyl orange appears red, while in alkaline conditions it appears yellow.
The examples of an indicator are-litmus paper, methyl orange, phenolpthalin etc.
methyl orange
Methyl orange is red under a pH=3,1 and yellow over a pH=4,4; methyl orange is useful for the titrimetric determination of acids concentration.
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.
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.
An acidic solution will turn methyl orange pink. Methyl orange is an acid-base indicator that changes color from red to yellow in acidic solutions and from yellow to pink in basic solutions.
Baking soda pH about 8.0 so methyl orange is yellow (above 4.4)
