氯化亚锡 化学式SnCl2。无色正交晶体;密度 3.95克／厘米3，溶点246℃，沸点652℃；易溶于水，也溶于乙醇、乙醚和丙酮等有机溶剂。商品常为二水合物SnCl2·2H2O，为无色单斜晶体，熔点37.7℃，密度2.71克／厘米3。 氯化亚锡在水溶液中会水解，产生白色的氢氧化亚锡沉淀： SnCl2+2H2O─→Sn(OH)2+2HCl如果溶液中存在盐酸，可抑制沉淀析出；如果盐酸浓度稍大,则形成SnCl娸。SnCl2有较强的还原性,在溶液中易被空气中的氧逐渐氧化,在光照下氧化作用加快。SnCl2还能使Hg(Ⅱ)盐还原为Hg，使Fe(Ⅲ)盐还原为Fe(Ⅱ)盐，使I2还原为I-。 在加热下，将金属锡溶于浓度为30％的盐酸中，然后将溶液放在充有二氧化碳气体和装有浓硫酸的干燥器中结晶，或将溶液在35～37℃和二氧化碳气氛下进行蒸发并冷却结晶，可得二水合氯化亚锡。将SnCl2·2H2O放在干燥的氯化氢气流中进行脱水,可得无水SnCl2。氯化亚锡主要做还原剂。
