The major uses of Nitrates especially Ammonium, Calcium and Potassium Nitrates are as fertilizer. Nitrates can be used in the manufacture of glass, nitrites, nitrous oxide, explosives, eutectic salts, pyrotechnics, matches, freezing mixtures and special cements. They are also used for coagulation of latexes, in the nuclear industry and as a corrosion control in aqueous systems.

Nearly all metal nitrates are readily soluble in water; for this reason they are often used when a water soluble salt of a metal is needed.

Nitrites are in the manufacture of diazo dyes and rubber, in the textile industry, in photography, and in the manufacturing of eutectic salts. Nitrites are also used in analytical and preparative chemistry, as a corrosion inhibitor and as an antidote in cyanide poisoning.

Both Nitrates and Nitrites can be used as a coloring and preserving additive for food. Hummel Croton Inc. does not supply food grade Chemicals.
