There are various ways to test for an acid and an alkali. For acidic solution: Litmus paper/ litmus solution --> red Phenolphthalein --> colorless Methyl orange --> pink Universal Indicator (changes color according to the strength of acid) --> red to yellow. For alkaline solutions: Litmus paper/ litmus solution --> blue Phenolphthalein --> pink Methyl orange --> yellow Universal Indicator --> blue green to purple
Historically, methyl-methyl ester. More modernly, the compound is called methyl methanoate.
Methyl Acetate
Methyl Propanoate.

The "methyl" and "methylene" come from their chemical structures. Something that has "methyl" in its name contains a methyl group - CH3. A common chemical like this is methyl alcohol - CH3OH. The methylene group is CH2. The blue and violet? That's what color they are.

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

Red+Blue=PURPLE Blue+Yellow=GREEN Yellow+Red= ORANGE
Methyl orange is also known as p-dimethylamino-azobenzenesulfonic ACID.As stated on wikipedia, hence I would have to say that it is in fact an acid, interestingly, it is an acid that tells us whether a substance is an acid or alkali, by changing colour.It is known as an INDICATOR.In:Acid=Red. Alkali=Yellow. Neutral=Orange, thus the name methyl orange.HAHA.There you go. A decent answer.Hope this helps.
* Blue * White * Yellow * Orange
Methyl Acetate
