Tin(II) chloride, also known as stannous chloride, is a white crystalline solid with the formula Sn Cl 2. It forms a stable dihydrate, but aqueous solutions tend to undergo hydrolysis, particularly if hot. SnCl 2 is widely used as a reducing agent (in acid solution), and in electrolytic baths for tin-plating.
Tin(II) chloride (also known as stannous chloride) is the most important commercial tin halide. Illustrating the routes to such compounds, chlorine reacts with tin metal to give SnCl 4 whereas the reaction of hydrochloric acid and tin produces SnCl 2 and hydrogen gas.
The stannous ion, commonly added to toothpastes as stannous fluoride or stannous chloride, has been shown to have antibacterial effects in the mouth. Research has shown that stannous fluoride-containing toothpaste inhibits extracellular polysaccharide ( EPS ) production in a multispecies biofilm greater than sodium fluoride-containing ...
Salt/common salt – a mineral, sodium chloride, NaCl, formed by evaporating seawater (impure form). Salt of tartar – potassium carbonate; also called potash. Salt of hartshorn/sal volatile – ammonium carbonate formed by distilling bones and horns. Tin salt – hydrated stannous chloride; see also spiritus fumans, another chloride of tin.
n.o.s. = not otherwise specified meaning a collective entry to which substances, mixtures, solutions or articles may be assigned if a) they are not mentioned by name in 3.2 Dangerous Goods List AND b) they exhibit chemical, physical and/or dangerous properties corresponding to the Class, classification code, packing group and the name and description of the n.o.s. entry [2]
At near-room temperature in liquid ammonia solution, the same reaction still gives a mixture of 60% stannous and 35% stannic sulfide. [7] Likewise metallic tin contaminates triaryltin sulfide pyrolysates. [7] At cryogenic temperatures, stannous chloride dissolves in liquid hydrogen sulfide. It then decomposes to the sulfide, but only slowly. [8]

In the in vitro method, some of the patient's blood is drawn and the stannous ions (in the form of stannous chloride) are injected into the drawn blood. The technetium is subsequently added to the mixture as in the in vivo method. In both cases, the stannous chloride reduces the technetium ion and prevents it from leaking out of the red blood ...
