Nitrate: In inorganic chemistry, a nitrate is a salt of nitric acid with an ion composed of one nitrogen and three oxygen atoms (NO₃). In organic chemistry the esters of nitric acid and various alcohols are called nitrates. Nitrogen trioxide is an alternative name for nitrate. ( source )

Nitrite: The nitrite ion is NO₂. The anion is bent, being isoelectronic with ozone. More generally, a nitrite compound is either a salt or an ester of nitrous acid. ( source )
