content="硫酸的物理性質(zhì)-山東坤春環(huán)?？萍加邢薰?　　純硫酸一般為無(wú)色油狀液體，密度1.84 g/cm3，沸點(diǎn)337℃，能與水以任意比例互溶，同時(shí)放出大量的熱，使水沸騰。加熱到290℃時(shí)開(kāi)始釋放出三氧化硫，最終變成為98.54%的水溶液，在317℃時(shí)沸騰而成為共沸混合物。硫酸的沸點(diǎn)及粘度較高，是因為其分子內部的氫鍵較強的緣故。由于硫酸的介電常數較高，因此它是電解質(zhì)的良好溶劑，而作為非電解質(zhì)的溶劑則不太理想。硫酸的熔點(diǎn)是10.371℃，加水或加三氧化硫均會(huì )使凝固點(diǎn)下降。 "> <meta name='viewport' content='width=1440' /> <link
