Is orange juice a acid or an alkali?

Answer 1

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.

Answer 2

orange juice is a acid at the pH scale of between 4 and 5

Answer 3

Orange Juice is acidic due to its citric acid content.
