tin ii chloride dihydrate formula, also called Stannous chloride, is a white crystalline substance. It forms a stable dihydrate, but aqueous solutions are prone to hydrolysis. It is commonly used as a reducing agent (in acid solution) and in tin-plating electrolytic baths.

Tin Chloride is a chemical that is made through dissolving tin in hydrochloric acid, followed by evaporation and crystallization. It then attracts oxygen from the air. This creates insoluble oxychloride, which is a two-part composite consisting of chlorine and an oxygen atom.

In textile dyeing, it’s used as a mordant to give brighter colors with some dyes such as cochineal, and in tooth pastes it can be added for protection against enamel erosion. It is also a catalyst in the production of polylactic acid.

It is used in a related reduction that was traditionally used as an analytical test for Hg2+ (aq). If SnCl2 is added dropwise to a solution of mercury(II) chloride, a white precipitate is first formed; as more SnCl2 is added this turns black as metallic mercury is formed.

Moreover, SnCl2 is a good reductant for copper(II). In the solid state, crystalline SnCl2 forms chains with chloride bridges as shown in the figure above.

The dihydrate is also three-coordinated, with one water on the tin and another on the first. The main part of the molecule stacks into double layers in the crystal lattice, and the “second” water is sandwiched between the layers.

Tin chloride is poisonous when ingested, and it irritates the eyes and skin as soon as it comes into contact with them. It is often utilised as a tanning agent, and it is widely used in the pharmaceutical industry.
