什么物质的量浓度的硫酸才叫浓硫酸?
硫酸的浓稀概念有一个大概的标准：最高的发烟硫酸密度约为2含游离的SO3约60%.一般来说密度为1.84的硫酸叫浓硫酸(注：我认为一般浓度70%以上的叫浓硫酸)其中折合含SO3的量达到82%,它的浓度为18 mol/L,中等浓度的是指密度在1.5到1.8左右,它们的浓度分别是在9.2mol/L到16mol/L.那么稀硫酸是指密度在1.5以下,浓度在9.2mol/L以下
The strong sulfuric acid dilute concept has a general standard:the highest fuming sulfuric acid density is about 2 including free SO3 about 60%.Generally speaking density 1.84 sulfuric acid that concentrated sulfuric acid (note:I think general concentration is more than 70% of the sulfuric acid) which reduced the amount of SO3 containing up to 82%,its concentration for and mol/L,medium concentration is refers to the density in 1.5 to 1.8,the concentration of them were in 9.2 mol/L to 16 mol/L.Then dilute sulphuric acid is refers to the density in 1.5 the following,concentration in 9.2 the mol/L
