SulphuricThe molecular formula isHtwoSOfour，molecular weight98.08. Sulfuric acid is the most commonly used inorganic acid. It can be diluted into different concentrations with water to reduce its risk. When the concentration is not specified, it refers to the industrial concentrated sulfuric acid with a content of 98%.

nature:Sulfuric acid is a colorless, transparent, oily liquid. boiling pointtwo70℃。冰點(diǎn)10.four℃。比重one8two—one8four。Sulfuric acid is one of the most active inorganic acids. It can react with almost all metals and their oxides and hydroxides to form sulfate. It can also interact with salts of other inorganic acids. Sulfuric acid has strong water absorption and oxidation. Contact with human body can cause serious burns. Sulfuric acid dissolves in water and gives off a lot of dilution heat. Therefore, only acid can be added to water during operation,Never add water to acid！ To prevent local overheating of acid liquid surface from causing explosion and acid spraying accident.

Purpose:Sulfuric acid is one of the important raw materials in chemical industry. It is widely used in chemical raw materials, dyes, medicine, food, printing and dyeing, leather, metallurgy and other industries. It is mainly used to make inorganic chemical fertilizer, especially phosphate fertilizer.

PCB industry is widely used in cleaning, electroplating, micro etching and other processes.
