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.
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.
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.
Methyl orange can also be separated using solvents such as ethanol, acetone, or methanol. These solvents can be used in a similar way as water to dissolve and separate the components of a mixture containing methyl orange.
the color of methyl orange in an acidic medium is orange
When titrating borax with HCl using methyl orange indicator, the color changes from yellow to orange as the end point is approached. This color change is due to the change in pH from basic (yellow) to acidic (orange) as the titration progresses.

The Screened Methyl Orange moves the furthest
Methyl orange can also be separated using solvents such as ethanol, acetone, or methanol. These solvents can be used in a similar way as water to dissolve and separate the components of a mixture containing methyl orange.
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.
Screened Methyl orange separates when it comes in contact with water on the filter paper because it is an impure substance and impure substances are made of 2 or more components......so therefore it separates the blue colou ration from the orange colouration
the color of methyl orange in an acidic medium is orange
Methyl orange is a polar compound.
When titrating borax with HCl using methyl orange indicator, the color changes from yellow to orange as the end point is approached. This color change is due to the change in pH from basic (yellow) to acidic (orange) as the titration progresses.
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.
