The sulfate nitrates are a family of double salts that contain both
sulfate and
nitrateions (NO3−, SO42−). They are in the class of
mixed anion compounds. A few rare minerals are in this class. Two sulfate nitrates are in the class of anthropogenic compounds, accidentally made as a result of human activities in fertilizers that are a mix of
ammonium nitrate and
ammonium sulfate, and also in the atmosphere as polluting
ammonia,
nitrogen dioxide, and
sulfur dioxide react with the oxygen and water there to form solid particles. The nitro group (NO3−) can act as a
ligand, and complexes containing it can form salts with sulfate.[1]
