What Are the Different Sulfuric Acid Products?

Pure sulfuric acid is a colorless and transparent oily liquid. Industrial products are yellowish or even brown due to impurities. The varieties are dilute acid with w (H2S0.) = 75% ~ 78%, concentrated sulfuric acid with u (H2S0.) = 93% or 98% (commonly known as 93 acid and 98 acid), and a volume fraction o ( SO.) = 20 or 65% (commonly known as 105 acid and 115 acid) fuming sulfuric acid. Sulfuric acid has a strong corrosive effect. Concentrated sulfuric acid will release a lot of heat through water, and it will have a strong dehydration effect on carbohydrates (such as cotton, linen, wood, etc.) or human skin. Store properly. Pay attention to safety when using, and beware of production and personal injury accidents. ^[1]
