Sulphuric acid is a highly corrosive and strong acid which is used in a wide number of processing and other applications. Here, we answer five of the most common sulphuric acid FAQs.
What are the main properties of sulphuric acid?
Sulphuric acid has the formula SO4. It is a clear or sometimes brown substance, with oily and odourless properties. It melts at 10 degrees Celsius and boils at 337 degrees Celsius. It is a highly corrosive substance, and even a small splash can burn the skin.
What are the applications for sulphuric acid?
Sulphuric acid has a number of industrial applications. However, the most common is in the processing of fertiliser. It is also used in some chemical processing, such as the making of dyes, detergents, hydrochloric acid, explosives, nitric acid, and medicines. You will find it in diluted amounts in some household products such as drain unblockers.
How can I neutralise sulphuric acid?
The easiest way to neutralise a sulphuric acid spill is with baking soda, an alkali which is commonly used to neutralise most acids. Slowly pour the baking soda over the entire contaminated area and allow the baking soda to absorb the acid. Wear gloves and ensure the room is well ventilated.
Can water be used to neutralise sulphuric acid?
No, it is not possible to neutralise sulphuric acid with water. However, it can be diluted with it. It is important to note that water and sulphuric acid cause an exothermic reaction, so drops of acid must be added carefully and with constant stirring.
Can sulphuric acid be used for anodising?
Yes, it can. Sulphuric acid can be used to create a strong surface with anti-corrosion properties for metals. It is chosen for its high degree of uniformity. Sulphuric acid anodising can only be carried out by specialists, such as https://www.poeton.co.uk/surface-treatments/anodising/sulphuric-acid-anodising.
This highly strong, oxidising acid has a wide range of industrial uses, and can even be found in products used in the home. A high degree of caution should be taken when using sulphuric acid as it has highly corrosive properties.
