Sulphuric acid is one of the most widely used chemicals in industry, known for its reactivity and versatility. You’ll find it in a wide range of applications – ranging from everyday household products to the more complex industrial processes. Its concentrated form is highly corrosive, so handling requires proper care and safety equipment.
Industrial Manufacturing
One of the main uses of sulphuric acid is in the production of fertilisers, particularly phosphate-based products. In these processes, sulphuric acid reacts with phosphate rock to produce phosphoric acid, which is then converted into various fertiliser products that help crops grow.
Beyond agriculture, sulphuric acid is heavily used in the manufacture of chemicals such as hydrochloric acid, nitric acid, and synthetic detergents. You’ll find that without sulphuric acid, so many of the products we take for granted, from soaps to plastics, would be far more expensive or even unavailable.
Metal Treatments
Another major use is in metal processing, including refining, cleaning, and coating processes. Sulphuric acid anodising, such as at www.poeton.co.uk/surface-treatments/anodising/sulphuric-acid-anodising, is a widely used method for producing durable, corrosion-resistant layers onto aluminium parts.
In this technique, aluminium components are immersed in a sulphuric acid bath while an electric current passes through, creating a protective oxide layer.
Batteries and Energy Storage
You’ll also find sulphuric acid playing a big role in energy storage, particularly in lead-acid batteries, which are still widely used in vehicles and backup power systems. In these batteries, the acid acts as an electrolyte, giving the chemical reactions that allow the battery to store and release electrical energy efficiently.
