Methyl orange is an acid/base indicator changing from orange-yellow to red when pH lowers from 4.4 to 3.1, thus indicating the endpoint (pH ~ 4) of the 'bicarbonate (HCO3-) to carbonic acid (H2CO3)'-titration with dilute strong acid (HCl).

What is the chemical formula for methyl orange?
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
When testing an unknown solution how can you tell if it is acidic basic or neutral?
Simple method is to use a pH testing kit. A more complicated method would be to perform a titration using methyl orange (or some other indicator).
What is the measure of how acidic or basic a solution is?
The pH scale measures how acidic or alkaline (basic) a solution is.
What is the difference between acidic solution and a basic solution?
An acidic solution contains H+ ions, a basic solution contains OH- ions.
What is used as an indicator of whether a solution is acidic or basic?
pH strips are used to determine whether a solution is acidic or basic
What color would methyl orange be in milk of magnesia?
Milk of magnesia is a basic solution. Therefore, methyl orange shows a yellowish orange colour. Further, this indicator shows a red colour in acidic solutions.

Substance that is of one color in an acid solution and of another color in a basic solution is a what?
An acid-base indicator. Some examples are phenolphthalein and methyl orange.
What is the action of caustic soda on colour of phenolphtalein?
Basic materials and any weak acid solution with pH above 4 turn Methyl Orange into orange-yellow

Is Seltzer basic or acidic?
The solution is acidic.
What is the difference between acidic solution and a basic solution?
An acidic solution contains H+ ions, a basic solution contains OH- ions.
What does yellow indicate on the ph scale?
It depends on what indicator you are using. Yellow with the bromothymol blue indicator is acidic, yellow with the methyl orange indicator is basic, yellow with the phenol red indicator is acidic and yellow with the universal indicator is acidic.
