Phenolphtalein remains colourless in acids, but turns pink in bases
Methyl Orange indicator turns pink in acids and yellow in bases
Acids turn litmus paper red
bases turn litmus paper blue
irrespective of which colour litmus paper is used
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.
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.
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.
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.

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 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.
