求翻譯:4.強酸性 純硫酸是無色油狀液體,10.4°C時凝固。加熱純硫酸時,沸點290°C,并分解放出部分三氧化硫直至酸的濃度降到98.3%為止,這時硫酸為恒沸溶液,沸點338°C。無水硫酸體現酸性是給出質子的能力,純硫酸仍然具有很強的酸性,98%硫酸與純硫酸的酸性基本上沒有差別,而溶解三氧化硫的發煙硫酸就是一種超酸體系了,酸性強于純硫酸。 是什么意思?![]() ![]() 4.強酸性 純硫酸是無色油狀液體,10.4°C時凝固。加熱純硫酸時,沸點290°C,并分解放出部分三氧化硫直至酸的濃度降到98.3%為止,這時硫酸為恒沸溶液,沸點338°C。無水硫酸體現酸性是給出質子的能力,純硫酸仍然具有很強的酸性,98%硫酸與純硫酸的酸性基本上沒有差別,而溶解三氧化硫的發煙硫酸就是一種超酸體系了,酸性強于純硫酸。
