Formula for tin ii fluoride

Tin II fluoride , commonly referred to commercially as stannous fluoride [1] [2] from Latin stannum , 'tin' , is a chemical compound with the formula SnF 2. It is a colourless solid used as an ingredient in toothpastes. Stannous fluoride was introduced as an alternative to sodium fluoride for the prevention of cavities tooth decay. It was introduced for this purpose by Joseph Muhler and William Nebergall. In recognition for their innovation, these two individuals were inducted into the Inventor's Hall of Fame. The fluoride in stannous fluoride helps to convert the calcium mineral apatite in teeth into fluorapatite , which makes tooth enamel more resistant to bacteria-generated acid attacks. The resulting fluoride-containing apatite is more insoluble, and more resistant to acid and tooth decay. In addition to fluoride, the stannous ion has benefits for oral health when incorporated in a toothpaste. At similar fluoride concentrations, toothpastes containing stannous fluoride have been shown to be more effective than toothpastes containing sodium fluoride for reducing the incidence of dental caries and dental erosion , [5] [6] [7] [8] [9] as well as reducing gingivitis. Stannous fluoride was once used under the trade name Fluoristan in the original formulation of the toothpaste brand Crest , though it was later replaced with sodium monofluorophosphate under the trade name Fluoristat. Although concerns have been previously raised that stannous fluoride may cause tooth staining, this can be avoided by proper brushing and by using a stabilised stannous fluoride toothpaste. Readily soluble in water, SnF 2 is hydrolysed. SnF 2 acts as a Lewis acid. The monoclinic form contains tetramers, Sn 4 F 8 , where there are two distinct coordination environments for the Sn atoms.

Nomenclature , a collection of rules for naming things, is important in science and in many other situations. The simplest of these are binary compounds , those containing only two elements, but we will also consider how to name ionic compounds containing polyatomic ions, and one specific, very important class of compounds known as acids subsequent chapters in this text will focus on these compounds in great detail. We will limit our attention here to inorganic compounds, compounds that are composed principally of elements other than carbon, and will follow the nomenclature guidelines proposed by IUPAC. The rules for organic compounds, in which carbon is the principle element, will be treated in a later chapter on organic chemistry. To name an inorganic compound, we need to consider the answers to several questions. First, is the compound ionic or molecular? If the compound is ionic, does the metal form ions of only one type fixed charge or more than one type variable charge? Are the ions monatomic or polyatomic?
