It's an indicator that turns red with acids and yellow with bases (though I prefer to use the term alkalis).
Actually, that answer is not strictly true because it will turn yellow at a pH of slightly less than pH 7 (neutral) so some weak acids will appear to be alkaline with this indicator.
acid base indicator or pH indicatorSome examples of acid base indicators are: gentian violet, malachite green, thymol blue, methyl yellow, bromophenol blue, congo red, methyl orange, screened methyl orange, bromocresol green, methyl red, methyl purple, phenolphthalein, indigo carmine, hydrangea flowers, anthocyanin, litmus, red cabbage, and purple cauliflower.
The effect of dilute HCl on the colors of the methyl orange will most likely be red. This is assumed because of both most likely having a pH of 3.1, which will end up red.
Methyl red will appear yellow in a boric acid solution and red in a mannitol solution.
Methyl orange is an acid-base indicator that changes color depending on the pH of the solution it is in. In an acidic solution, methyl orange appears red, while in a basic solution, it appears yellow. The reaction involves protonation of the indicator molecule in acidic conditions, leading to a color change.
Sulfuric acid will turn red when methyl orange is added, indicating that the solution is highly acidic.

there are many types of acid base indicators - see chart at http://chemistry.about.com/library/weekly/aa112201a.htm Common indicators: Methyl orange - acid=red, base=orange Bromcresol green - acid=yellow, base=blue Bromphenol blue - acid=yellow, base=blue Phenolphthalein - acid=colorless, base=red it is also easy to use litmus paper - acid=red, base=blue
Methyl Red, methyl orange, bromophenol blue, phenolphthalein, thymolphthalein, bromocresol green, bromothymol blue are all used as acid base indicators.
there are other indicators that can be used - universal Acid-red Base-Blue Neutral-green methyl orange Acid - red Base - yellow
Methyl orange is an acid-base indicator that changes color depending on the pH of the solution it is in. In an acidic solution, methyl orange appears red, while in a basic solution, it appears yellow. The reaction involves protonation of the indicator molecule in acidic conditions, leading to a color change.
Sulfuric acid will turn red when methyl orange is added, indicating that the solution is highly acidic.
An acidic solution will turn methyl orange pink. Methyl orange is an acid-base indicator that changes color from red to yellow in acidic solutions and from yellow to pink in basic solutions.
Hydrochloric acid is an acid, so it reacts with methyl orange, which is a pH indicator. When added to hydrochloric acid, methyl orange turns red due to the low pH of the acid. This color change indicates the presence of an acidic solution.
The solution of NaOH in methyl orange indicator will turn from yellow to red. Methyl orange is an acid-base indicator that changes color in response to a change in pH. In the presence of a strong base like NaOH, the indicator will change to a red color indicating the basic nature of the solution.
The color of methyl orange is red. The color is red when the acetic acid is below pH 3.1.
