Sulfuric acid (H2SO4) is a highly corrosive mineral acid that is widely used in the United States, with millions of tons produced each year. It is a heavy, aggressive chemical that poses serious challenges for safe storage due to its ability to corrode various materials, including metals, living material, stone, and plastic.
The corrosiveness of sulfuric acid is primarily due to its strong acidic nature, and it becomes even more corrosive at higher concentrations. At high concentrations, it exhibits strong dehydrating and oxidizing properties, posing serious risks upon contact. It can cause chemical burns through hydrolysis and secondary thermal burns through dehydration. If it comes into contact with the eyes, it can lead to permanent blindness, and ingestion can cause irreversible damage.
Sulfuric acid's corrosive nature also extends to plastics, as it can break down plastic materials by reacting with their polymer chains. This reaction causes the plastic to weaken and degrade, resulting in a loss of structural integrity and physical properties. Therefore, it is recommended to use materials that are resistant to sulfuric acid, such as glass or certain types of plastics like polyethylene, when handling this substance.
The safe storage of sulfuric acid requires specific tank systems that can withstand its corrosive effects. Poly Processing, for example, offers tanks and fittings specifically designed to store sulfuric acid and reduce associated risks. Their OR-1000™ system, which includes features like PVC fittings, Viton Gaskets, and stainless steel bolts, is tailored to different concentration ranges of sulfuric acid, ensuring safe and effective storage.

It can burn through most types of plastic
Sulphuric acid is a highly corrosive mineral acid that is widely used in the United States. It is a heavy chemical with a molecular weight of 98.079 g/mol, which will test the mechanical integrity of any material it comes into contact with. This includes plastics, which sulphuric acid can burn through by breaking down their polymer chains. This causes the plastic to weaken and degrade, resulting in a loss of structural integrity.
However, it is important to note that not all plastics are susceptible to sulphuric acid in the same way. Some types of plastics, like polyethylene, are more resistant to the acid's corrosive properties. Additionally, the concentration of sulphuric acid plays a role in its corrosive ability. At high concentrations, sulphuric acid can cause serious damage to materials, including metals, living material, stone, and plastic.
The corrosiveness of sulphuric acid is due to its strong acidic nature and its ability to exhibit dehydrating and oxidizing properties when concentrated. This can result in chemical burns through hydrolysis and secondary thermal burns through dehydration. If it comes into contact with the eyes, it can cause permanent blindness, and if swallowed, it can cause irreversible damage.
When sulphuric acid touches human skin, its first reaction is to absorb water, which is exothermic and can lead to chemical burns. The acid causes damage to the skin by hydrolysing proteins on the surface, which requires the presence of water to proceed at a reasonable rate. Therefore, without sufficient water or an input of heat, there is no immediate mechanism for the acid to start attacking the skin.
In summary, sulphuric acid is a highly corrosive substance that can burn through most types of plastic. However, certain types of plastics, such as polyethylene, are more resistant to its effects, and the concentration of the acid also plays a role in its corrosive ability. The corrosiveness of sulphuric acid poses serious challenges to its storage and handling, requiring specific materials and safety precautions to prevent accidents and harm to people and the environment.

It cannot burn through plastic pipettes
Sulfuric acid is a highly corrosive mineral acid that is widely used in the United States. It is a heavy chemical with a molecular weight of 98.079 g/mol, which will test the mechanical integrity of any material it comes into contact with. This includes plastics, which sulfuric acid can break down by reacting with their polymer chains, causing them to weaken and degrade.
However, it's important to note that not all plastics are the same, and some may be more resistant to sulfuric acid than others. The strength of plastic depends on the type of polymer chains it is made up of and the strength of the bonds between them. While sulfuric acid can break down certain plastics, it may not be able to break down others with stronger bonds.
In the context of plastic pipettes, it is generally advised to use pipettes made of materials that are resistant to sulfuric acid, such as glass or certain types of plastics like polyethylene. This suggests that sulfuric acid can indeed burn through some types of plastic pipettes, but not all.
Therefore, it is crucial to exercise caution when using sulfuric acid with plastic materials. While it may not immediately burn through a plastic pipette, prolonged exposure or higher concentrations of the acid could potentially lead to degradation and loss of structural integrity. Additionally, if the sulfuric acid comes into contact with skin, it can cause serious chemical and thermal burns, permanent blindness, and irreversible damage if swallowed.
