Tin(II) chloride is a white crystalline solid whose formula is Sn Cl2. It forms a stable dihydrate, but aqueous solutions tend to undergo hydrolysis, especially when heated. SnCl2 is widely used as a reducing agent (in acid solution) and in electrolytic baths for tin coating. Tin(II) chloride should not be confused with other tin chlorides; Tin (IV) chloride (SnCl4).
Tin(II) chloride is used as a reducing agent in the laboratory. In electroplating, it is used for electroplating.
Tin(II) chloride is used in chemical analysis, in dyeing to reduce indigo and iron and manganese oxide on witnesses, as mordant, namely for cochineal dyeing, for lightening and brightening, also for rendering gold purple and lacquer colors , as anti-chlorine and for removing rust stains from laundry.
Tin(II) chloride, dissolved in concentrated hydrochloric acid, is used as a detecting agent for arsenic in the Bettendorf sample. The solution turns brown because tin(II) chloride reduces the arsenic compound and precipitates elemental arsenic. The only disturbing elements are mercury and precious metals. This reagent can also be used to detect sesame oil as the solution turns red when layered with sesame oil.
