Calcium nitrite, with the chemical formula Ca(NO2)2 and CAS number 13780-06-8, is an inorganic compound that appears as a white to yellowish solid. It is highly soluble in water, forming a clear solution that can be slightly alkaline. Calcium nitrite is primarily used as a corrosion inhibitor in concrete and as a food preservative due to its ability to prevent the growth of harmful bacteria. It serves as a source of nitrite ions, which can react with amines to form nitrosamines, a concern in food safety. In addition, it is utilized in the production of fertilizers and as a component in various chemical syntheses. The compound is hygroscopic, meaning it can absorb moisture from the air, which can affect its stability and handling. Safety precautions are necessary when working with calcium nitrite, as it can be harmful if ingested or inhaled, and it may cause skin and eye irritation. Proper storage in a cool, dry place is recommended to maintain its integrity.

Calcium nitrite is a white crystalline solid that is soluble in water. It has a high activity index and can be used as an inhibitor for corrosion of metals. Calcium nitrite also has a thermodynamic data from water vapor, which is the driving force in its solubility. The electrochemical impedance spectroscopy of calcium nitrite has been studied and found to have an intermolecular hydrogen bonding effect with the chloride ion and sodium citrate. These interactions are responsible for the increased solubility and decreased viscosity of calcium nitrite solutions.
