What Are the Hazards of Dilute Sulfuric Acid
Posted Date:2020/12/18
First of all, we can understand the harmful classification of dilute sulfuric acid through the GHS system:
Dilute sulfuric acid refers to an aqueous solution of sulfuric acid with a mass fraction of solute less than or equal to 70%. Since the sulfuric acid molecules in dilute sulfuric acid have been completely ionized, so it does not have the strong oxidizing, water-absorbing, and dehydrating properties of concentrated sulfuric acid (commonly known as carbonization, that is, strong corrosiveness) and other special chemical properties.
Dilute sulfuric acid CAS: 7664-93-9
