phenylmercuric denoting a compound containing the radical C6H5Hg—, forming various antiseptic, antibacterial, and fungicidal salts; compounds of the acetate and nitrate salts are used as bacteriostatic pharmaceutical preservatives, and the former is used as a herbicide.

Potassium nitrate is a chemical compound with the chemical formula KNO3. A naturally occurring mineral source of nitrogen, KNO3 constitutes a critical oxidizing component of black powder/gunpowder. In the past it was also used for several kinds of burning fuses, including slow matches.

Silver nitrate, also known as lunar caustic, is a soluble chemical compound with chemical formula AgNO3. This compound is a versatile precursor to many other silver compounds, such as those used in photography. Comparatively, it is far less sensitive to light than the halides.

Zinc nitrate (Zn(NO3)2) is a chemical compound used as a mordant in dyeing. It is also a source of zinc ions for chemistry. An example reaction gives a precipitate of zinc carbonate: Zn(NO3)2 + Na2CO3 → ZnCO3 + 2 NaNO3.
