Comparison between high concentration sulfuric acid and dilute sulfuric acid

Date:2017-04-10 Author:盛?;?/span> Click:

Comparison between high concentration sulfuric acid and dilute sulfuric acid: There is a general standard for the concept of concentrated sulfuric acid: the highest density of fuming sulfuric acid is about 2, and it contains about 60% of free SO3. Generally speaking, sulfuric acid with a density of 1.61g/mL is called concentrated sulfuric acid (note: sulfuric acid with a concentration of over 70% is generally considered concentrated sulfuric acid). The equivalent content of SO3 reaches 82%, and its concentration is 18 mol/L. Medium concentration refers to a density of around 1.5 to 1.8, and their concentrations are respectively 9.2mol/L to 16mol/L. So dilute sulfuric acid refers to a density below 1.5g/mL and a concentration below 9.2mol/L
