What is the chemical formula for methyl orange?

Answer 1

Methyl orange is synthesized by reaction of sulfanilic acid, sodium nitrite, and dimethylaniline. First, sulfanilic acid is dissolved in dilute aqueous acid. Sodium nitrite is added to produce a disowning salt .

Chemical formula of Methyl Orange: C14H14N3NaO3S

Answer 2

Here is the structure of methyl orange in acidic solution: http://antoine.frostburg.edu/chem/senese/101/features/images/methylorangeacidic.gifMethyl orange in acidic solution. Click the image for a 3D Chime structure. The molecule absorbs blue-green light, which makes its solution appear red. Notice that the nitrogen bearing the positive charge is involved in a double bond. In the basic form of methyl orange, a hydrogen ion is lost from the -NN- bridge between the rings, and the electrons formerly used to bind the hydrogen neutralize the positive charge on the terminal nitrogen, so that it is no longer able to pi-bond. Solutions of the methyl orange appear yellow in alkaline solution. http://antoine.frostburg.edu/chem/senese/101/features/images/methylorangebasic.gifMethyl orange in basic solution.

Answer 3

Methyl Orange is orange but is red in very acidic solution.

Answer 4

Methyl orange's molecular formula is written as C14H14N2NaO3S. This material is used as a pH indicator due to its distinct color change between red and yellow from ranges of pH 3.1 to 4.4.

Answer 5

An orange is acidic, about 1-3 on a pH scale. i hope that's what you're looking for. When you eat them, your mouth goes really acidic!

Answer 6

Co SO4
