Acid is a compound that, in solution in an
ionizing solvent (usually water), gives rise
to hydrogen ions. In modern chemistry, acids
are defined as substances that are proton
donors and accept electrons to form ionic
bonds. Acids react with bases to form salts,
and they act as solvents. Strong acids are
corrosive whilst diluted acids have a sour
or sharp taste, although in some organic
acids this may be partially masked by other
flavour characteristics. Acids can be
detected by using coloured indicators such
as litmus and methyl orange. The strength of
an acid is measured by its hydrogen-ion
concentration, indicated by the pH value.
The first known acid was common every-day
vinegar.
