Acid, any substance that in water solution tastes sour, changes the color of certain indicators (e.g., reddens blue litmus paper), reacts with some metals (e.g., iron) to liberate hydrogen, reacts with bases to form salts, and promotes certain chemical reactions (acid catalysis).
ACID definition: a compound usually having a sour taste and capable of neutralizing alkalis and reddening blue litmus paper, containing hydrogen that can be replaced by a metal or an electropositive group to form a salt, or containing an atom that can accept a pair of electrons from a base. Acids are proton donors that yield hydronium ions in water solution, or electron-pair acceptors that ...
CO 2 dissolves in water to give carbonic acid, SO 3 gives sulfuric acid, and P 4 O 10 reacts with water to give phosphoric acid. Metal oxides, on the other hand, are bases. Metal oxides formally contain the O 2- ion, which reacts with water to give a pair of OH - ions. Metal oxides therefore fit the operational definition of a base.
