The calcium type, also called Norgens-salpeter, inhibits steel corrosion by reacting with ferrous ions.
In oceanography, the f-ratio is the total primary production of organic compounds caused by them.   They have a trigonal planar arrangement, and are a hybrid of resonance structures that give each of their oxygen atoms either a double bond or a formal charge of minus one.  The copper type can be impregnated on zeolites, forming a catalyst useful in treating diesel fumes, while their hydroxylamine variety undergoes violent autocatalysis. The calcium type, also called Norgens-salpeter, inhibits steel corrosion by reacting with ferrous ions. The sodium salt combines with sulfuric acid and then can be fractionally distilled to form sodium bisulfate and nitric acid. The ammonium and potassium varieties are powerful oxiders used in fertilizers and explosives. FTP, name this polyatomic ion with formula NO3 [N O 3] minus.
