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 with lead forms a eutectic mixture at the weight proportion of 61.9% tin and 38.1% lead (the atomic proportion: 73.9% tin and 26.1% lead), with melting temperature of 183 °C (361.4 °F). Such solders are primarily used for joining pipes or electric circuits .
The compound is prepared by a redistribution reaction by combining stannic chloride and tetrabutyltin: 3 (C 4 H 9) 4 Sn + SnCl 4 → 4 (C 4 H 9) 3 SnCl. Tributyltin chloride hydrolyzes to the oxide [(C 4 H 9) 3 Sn] 2 O Tributyltin chloride is used as a precursor to other organotin compounds [1] and reagents, such as tributyltin hydride.
Organotin compounds are those with tin linked to hydrocarbons. The compound on the picture is trimethyltin chloride, an example of organotin compounds.. Organotin chemistry is the scientific study of the synthesis and properties of organotin compounds or stannanes, which are organometallic compounds containing tin–carbon bonds.
The hydrochloric acid provides a ready supply of chloride ions (Cl −), which react with the gold ions to produce tetrachloroaurate(III) anions ([AuCl 4] −), also in solution. The reaction with hydrochloric acid is an equilibrium reaction that favors formation of tetrachloroaurate(III) anions.
They have three butyl groups covalently bonded to a tin(IV) atom. [5] A general formula for these compounds is (CH 3 CH 2 CH 2 CH 2) 3 Sn−X. The −X is typically a chloride −Cl, hydroxide −OH, or a carboxylate RCO 2 −, where R is an organyl group. [6]
