3.1-4.4
from red to yellow
Phenolphthalein has a pH range of 8.2 to 10.0, where it changes color from colorless to pink. Methyl orange has a pH range of 3.1 to 4.4, exhibiting a color change from red at low pH to yellow at high pH.
A base is yellow with methyl orange.
The color of methyl orange is red. The color is red when the acetic acid is below pH 3.1.
The Screened Methyl Orange moves the furthest
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.

the color of methyl orange in an acidic medium is orange
Methyl orange is a polar compound.
IN ACID: it turns methyl orange pink In base: it turns methyl orange yellow
Methyl orange is yellow in alkaline conditions.
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 changes colors while in the middle of the acidic range so it is only used as an indicator to determine just how acidic a solution is. Below a pH of 3.1 it is red. As pH gets higher it goes to an orange color until it gets above a pH of 4.4 where it will be yellow.
Methyl orange and screened methyl orange are both synthetic dyes commonly used as indicators in titrations. They both change color at specific pH ranges: methyl orange transitions from red to yellow in acidic solutions, while screened methyl orange transitions from yellow to red in basic solutions. Both dyes are water-soluble and widely available for laboratory use.
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.
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 appears yellow in alkaline solutions.
Methyl orange is a pH indicator having the chemical formula C14H14N3NaO3S.
