acid

Burns litmus red

Acid is a substance with a sour taste that reacts with bases and turns litmus paper red.

The word extends to anything sharp or biting: acid wit, acid remarks.

In chemistry, acids are compounds that donate hydrogen ions.

Acid is also slang for LSD, the hallucinogenic drug: dropping acid.

As an adjective, acid describes sourness or corrosiveness: an acid taste, acid rain. (All-caps ACID is a database acronym.)
