Sulfuric Acid
What is Sulfuric Acid?
Sulfuric Acid is a highly corrosive, inorganic, strong mineral acid with the molecular formula H2SO4. It is a pungent, colorless to slightly yellow viscous liquid that is soluble in water at all concentrations. One of its primary uses includes pH adjustment to give alkaline fluids a neutral pH of 7.
Sulfuric Acid shows different properties depending upon its concentration. Its corrosiveness on other materials, like metals, living tissues, or even stones, can be mainly attributed to its strong acidic nature and, if concentrated, strong dehydrating and oxidizing properties.
What is the safest way to store Sulfuric Acid?
Assmann recommends that tanks be constructed of Linear Polyethylene. Assmann’s Linear polyethylene has an ESCR value of >1000 Hrs. Our Linear material is a .938 density and should not be confused with “High Density Linear Polyethylene.” Assmann’s .938 density material has a higher environmental stress cracking resistance than our competitors, due to the much higher cure rate our experts achieve by using LLDPE resin with other 9001 Certified processes.
What is the Specific Gravity of Sulfuric Acid?
The Specific Gravity of Sulfuric Acid changes based on its concentration. Read our chemical guide below for more details.
Are there additional considerations for storing Sulfuric Acid?
Sulfuric Acid is highly corrosive and can dissolve most metals. It’s important to keep Sulfuric Acid stored away from incompatible materials.

Common Industries
Sulfuric Acid has a wide range of applications in various industries, including those listed here.
Agriculture & Fertilizer
The most common use for Sulfuric Acid is in the agriculture industry, specifically in fertilizer. Sulfuric Acid is used to create inorganic phosphate fertilizers such as ammonium sulfate and superphosphate, which are both widely used fertilizers in commercial agriculture.
Chemical Manufacturing
In Chemical industries, Sulfuric Acid can be used as a component when creating other acids, such as hydrochloric and nitric acid.
Metal Processing
Sulfuric Acid is also used for metal processing as a key ingredient in what is known as “steel pickling,” a surface treatment process that removes rust or carbon impurities.

The Assmann Way
The Assmann difference is in the process. Assmann keeps quality first and failure far out of mind.
Uniform Wall Thickness
Uniform wall thickness provides better structural integrity compared to other tanks on the market. Because of its unified durability throughout, Assmann storage solutions are less susceptible to tears and spills, protecting your facility from the corrosive qualities of Sulfuric Acid. Because of the much higher cure rate our experts achieve by using LLDPE resin with other 9001 Certified processes, Assmann tanks are less prone to cracking.
Air Cooling
Air cooling eliminates a process related stress in rotomolding, where water cooling shocks the plastic and causes an abrupt stop to the curing process. Assmann is the only manufacturer who uses non-shielded molds with low temperature heat and gradual air cooling to ensure reliability that lasts.
Specific Gravity
Using a 2.2 rated tank gives additional wall thickness to help extend the lifespan of the storage tank. Assmann offers 2.2 rated storage tanks in either crosslink or linear polyethylene. For storing Sulfuric Acid, we recommend linear polyethylene.
Venting
Under-venting is one of the most common causes for tank failure. When filling and draining tanks, it’s important to keep the tank from vacuum and pressure exposure. A vent two times the size of your largest inlet is required to avoid pressurization. Sometimes a larger vent is necessary when tanks are pneumatically filled. Assmann offers a variety of venting options in multiple sizes and configurations.
How to Avoid Tank Problems
Although our uniform wall tanks help prevent UV damage, Sulfuric Acid storage should be kept away from direct sunlight to avoid rising temperatures.
Chemical Handling
Diluting Sulfuric Acid is a common practice across industries. However, our experts recommend keeping Sulfuric Acid pure, without dilution. When diluted, Sulfuric Acid can create an exothermic reaction, causing temperatures to spike above our tanks rating.
