Methyl Orange is an indicator that is used to indicate the equivilance point of and acid-base titration. In acidic environments, it turns red and in basic environemnts, or pH of 4.4 and higher, it turns yellow. It is prepared by treatment of helianthine with sodium hydroxide , helianthine is obtained by coupling diazotised sulphanilic acid with N,N-dimethylaniline .
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 soluble in HOT water, but why is it solube in water no informations were found.A simple answer would be: " If it is soluble in water is because it has properties which allows it to be soluble in water"
the color of methyl orange in an acidic medium is orange
Screened methyl orange is a pH indicator consisting of a solution of methyl orange and xylene cyanol in ethanol. It is red in very acidic solution, grey in neutral solution, and green in very alkaline solution.
IN ACID: it turns methyl orange pink In base: it turns methyl orange yellow
The government does not want people to use methyl and it is illegal.
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 typically available in two forms, mono-sodium salt and mono-ammonium salt. The mono-sodium salt form of methyl orange is more soluble in water compared to the mono-ammonium salt form.

Methyl orange is a polar compound.

IN ACID: it turns methyl orange pink In base: it turns methyl orange yellow
Methyl orange is commonly used as an indicator in paper chromatography. By placing a drop of the methyl orange solution onto the paper and allowing it to dry, when the paper is placed in a solvent, the components will move up the paper at different rates based on their chemical properties. This allows for separation and identification of the components in the mixture.
Methyl orange is yellow in alkaline conditions.
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.
