Question

A few drops of methyl orange are added to a soap solution.what color it changes into?

Answer 1

The soap solution will change into yellow color

Answer 2

Answer: Yellow color

Explanation:

Soap is generally alkaline in nature, so the soap solution will be alkaline. Thus, phenolphthalein shows a pink color in soap solution.

Methyl orange has a red color in an acidic environment and a yellow color in an alkaline environment. The soap solution is alkaline in nature and turns the color of the solution yellow.

Methyl orange is a pH indicator used in titrations because of its clear and distinct color change. It shows red color in acidic and yellow color in basic medium.

So when a few drops of methyl orange is added to a soap solution then it changes into yellow color.

Electrolysis of brine or sodium chloride solution produces sodium hydroxide, NaOH, which is a strong base. Using methyl orange as an indicator, a yellow NaOH solution is obtained.
