  • 产品描述:氢氟酸(简称HF)是氟化氢气体的水溶液，又称为氟酸、白骨酸、化骨水、洗钻水、除锈剂、酸洗，常温下为无色透明至淡黄色冒烟液体，有刺激性气味，比重0.98，比水略轻，沸点19.4℃，极易挥发，置空气中，即发白烟。含氟化氢60％以下的水溶液，为无色澄清的发烟液体。工业产品通常为HF含量40～45％的水溶液。有刺激性气味，与三氧化硫或氯磺酸生成氟磺酸，与卤代芳烃、醇、烯、烃类反应生成含氟有机物， 溶于水生成腐蚀性很强的酸，为中等强度的酸。有剧臭，性极毒，触及皮肤易致溃烂，其程度较任何酸厉害，若吸入它的蒸气，可以致命，所以使用时必须严格注意。 1.氢氟酸亦能与一般金属、金属氧化物、以及氢氧化物相作用，生成各种金属氟盐，但作用不及盐酸那样剧烈。金、铂、铅、石蜡以及某些塑料(聚乙烯等)与它不起作用，所以可作容器。 2.腐蚀性极强，能侵蚀玻璃和硅酸盐而生成气态的四氟化硅。反应式如下：SiO2＋4HF→H2O＋SiF4↑，玻璃是硅的化合物，因此氢氟酸不能盛放玻璃容器中。 3.氢氟酸能形成酸式盐，氢氟酸本是一元酸，但能制得一系列的酸式盐如NaHF2、KHF2、NH4HF2等 ，这是其他三种氢卤酸。 4.氢氟酸的弱酸性，因为氢原子和氟原子间结合的能力相对较强，使得氢氟酸在水中不能完全解离。在氢卤酸中只有氢氟酸是弱酸（其电离常数为3.5x10^-4，在浓度为 0.1mo1.L^-1 时它的表观电离度为 10％，因此，HF也可以勉强算作一个中强酸。浓时的电离度比稀时大而与一般弱电解质有别）。
