硫酸的濃稀概念有一個大概的標準：最高的發(fā)煙硫酸密度約為2含游離的SO3約60%.一般來說密度為1.84的硫酸叫濃硫酸(注：我認為一般濃度70%以上的叫濃硫酸)其中折合含SO3的量達到82%,它的濃度為18 mol/L,中等濃度的是指密度在1.5到1.8左右,它們的濃度分別是在9.2mol/L到16mol/L.那么稀硫酸是指密度在1.5以下,濃度在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
