数滴浓硫酸迅速蚀穿毛巾。

硫酸(化学分子式为H2SO4)是一种具有高腐蚀性的强矿物酸,一般为透明至微黄色,在任何浓度下都能与水混溶并且放热。有时,在工业制造过程中,硫酸也可能被染成暗褐色以提高人们对它的警惕性。

作为二元酸的硫酸在不同浓度下有不同的特性,而其对不同物质,如金属、生物组织、甚至岩石等的腐蚀性,都归根于它的强酸性,以及它在高浓度下的强烈脱水性与氧化性。硫酸能对皮肉造成极大的伤害,因为它除了会透过酸性水解反应分解蛋白质及脂肪造成化学烧伤外,还会与碳水化合物发生脱水反应并造成二级火焰性灼伤;若不慎入眼,更会破坏视网膜造成永久失明。故在使用时,应做足安全措施。另外,硫酸也是潮解性的,会吸取空气中的水蒸气。
