Harm of sulfuric acid

Hazards of sulfuric acid:

1, sulfuric acid has a strong stimulating and corrosive effect on skin, mucosa and other tissues.

2, steam or fog can cause conjunctivitis, conjunctival edema, corneal opacity, and even blindness.

3, causing respiratory irritation, severe dyspnea and pulmonary edema.

4, high concentration caused by laryngeal spasm or glottic edema and suffocation.

5. After oral administration, digestive tract burns and ulcers form.

6, severe cases can have gastric perforation, peritonitis, kidney damage, shock, etc.

Extended data:

Sulfuric acid (chemical formula: H2SO4), the most important oxyacid of sulfur. Anhydrous sulfuric acid is a colorless oily liquid which crystallizes at 65438 00.36℃. Usually, aqueous solutions with different concentrations are used and prepared by tower method and contact method. The former is crude dilute sulfuric acid with mass fraction of about 75%. The latter can obtain 98.3% concentrated sulfuric acid with boiling point of 338℃ and relative density of 1.84.

Sulfuric acid is the most active binary inorganic strong acid, which can react with most metals. High concentration sulfuric acid has strong water absorption, and can be used as dehydrating agent to carbonize carbohydrate-containing substances such as wood, paper, cotton and linen fabrics, biological skins and meat. When it is mixed with water, it also releases a lot of heat energy. It is corrosive and oxidizing, so it should be used with caution.

It is an important industrial raw material, which can be used to make fertilizers, drugs, explosives, pigments, detergents, batteries and so on. , also widely used in petroleum purification, metal smelting, dyes and other industries. Commonly used as chemical reagent, it can be used as dehydrating agent and sulfonating agent in organic synthesis.
