nitrate Salt of nitric acid. Nitrate salts contain the nitrate ion (NO3) and some are important, naturally occurring compounds such as saltpetre (potassium nitrate, KNO3) and Chile saltpetre (sodium nitrate, NaNO3). Nitrates are used as food preservers, fertilizers, explosives, and as a source of nitric acid. They can be an environmental hazard.
