(n.) One of a class of compounds, generally but not always distinguished by their sour taste, solubility in water, and reddening of vegetable blue or violet colors. They are also characterized by the power of destroying the distinctive properties of alkalies or bases, combining with them to form salts, at the same time losing their own peculiar properties.

Those which contain no oxygen are sometimes called hydracids in distinction from the others which are called oxygen acids or oxacids.
