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 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.
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 turns yellow when dipped in a base.
Methyl orange will turn yellow in a soap solution.
