A sour
substance.
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. They all contain hydrogen, united
with a more negative element or radical, either alone, or more generally
with oxygen, and take their names from this negative element or radical.
Those which contain no oxygen are sometimes called hydracids in
distinction from the others which are called oxygen acids or
oxacids.
