Nitric acid
(HNO3) is a colorless, liquid acid widely used in the manufacturing of
explosives and fertilizers. When dissolved in water, molecules of nitric acid
separate (or dissociate) into hydrogen ions (H+) and nitrate ions (NO3). The
fact that nearly every nitric acid molecule dissociates is what makes nitric
acid a strong acid. Nitric acid is often the starting material in the
industrial production of nitrates for fertilizers.
Nitric acid is
also formed from the reaction of nitrogen oxides produced during the combustion
(burning) of fossil fuels in automobile engines. These nitrogen oxides react
with water in the atmosphere and form nitric acid, one cause of acid rain. High
levels of nitrates in drinking water can contribute to the formation of nitrosamines,
a group of carcinogenic (cancer causing) compounds.
